The decision of the Authority follows:
31 FLRA NO. 14 OVERSEAS EDUCATION ASSOCIATION Union and DEPARTMENT OF DEFENSE DEPENDENTS SCHOOLS, ATLANTIC REGION Agency Case No. O-AR-1363 DECISION I. Statement of the Case This matter is before the Authority on exceptions to the award of Arbitrator Stanley H. Sergent, Jr. filed by the Agency under part 7122(a) of the Federal Service Labor - Management Relations Statute (the Statute) and part 2425 of the Authority's Rules and Regulations. The Union filed an opposition to the Agency's exceptions. The Arbitrator found that the increase in the number of classes the grievant was required to teach was not a change in the conditions of her employment or a violation of past practice. Rather, he found that the change was an exercise of management's rights under section 7106 of the Statute. However, he also found that there were no precise standards in the parties' collective bargaining agreement, law or regulation to enable him to resolve the issue of whether the grievant was entitled to a salary increase. The Arbitrator directed the parties to initiate the necessary action to have a wage survey conducted and the results applied retroactively to the grievant. He also sustained the Union's claim for official time and travel expenses for one of its witnesses but denied the Union's request for attorney fees. The Agency alleges that the award is contrary to law and that the Arbitrator exceeded his authority. We conclude that the Agency has failed to establish that the award is deficient as alleged. However, the award must be modified to provide that the results of any wage survey conducted as a consequence of the Arbitrator's award are to be applied to the grievant prospectively. II. Background The grievant is a teacher of home economics at the Lakenheath High School in England. She was hired as a half-time teacher to teach three class periods out of a six class period instructional day. At the beginning of the 1985-86 school year, the instructional day was increased to seven class periods and each class period was reduced from 55 to 45 minutes. The grievant was notified that because of the increase in the number of class periods in the instructional day and the increase in the enrollment in home economics, she was to teach four class periods each day. The grievant did not receive any pay increase for teaching the additional class period. The Union requested bargaining over the change in the grievant's working conditions under Article 7 of the parties' collective bargaining agreement. Article 7 establishes the contractual procedure regarding notification to the Union about proposed changes in working conditions of bargaining unit employees and the obligation of the parties to negotiate over those changes. The Agency did not bargain with the Union over the alleged changes in the grievant's conditions of employment. A grievance was filed protesting the increase in the grievant's duties. The grievance alleged that by increasing the number of class periods that the grievant was required to teach, the Agency changed her conditions of employment and violated a long-standing past practice of requiring half-time teachers to teach only three class periods in the instructional day. The grievance also alleged that as a result of the increase in the number of class periods the grievant was required to teach, she was teaching approximately two-thirds of the instructional day for half pay. The Union alleged that "(t)his change was implemented contrary to the governing contractual procedures, and, further, is in conflict with DODDS' directives and/or salary setting guidelines." Award at 3. As a remedy, the Union requested: (1) that the grievant's three class period schedule be reinstated until the Agency complied with Article 7 of the parties' agreement; (2) that the grievant receive pay calculated at two-thirds of the daily rate for similarly, situated full-time teachers rather than at one-half of the daily rate for the time during which she taught the four class periods; and (3) "any . . . other relief that an arbitrator may deem necessary or appropriate." Award at 3. The grievance was submitted to arbitration. III. The Arbitrator's Award The parties were unable to agree on the formulation of an issue. Consequently, each party submitted a separate statement of the issue or issues in the case to the Arbitrator. The Union submitted the following issue: Did the management of the Department of Defense Dependents Schools violate the collective bargaining agreement with the OEA or applicable law, government regulations, directives, or policies by unilaterally assigning half-time teachers, including (the grievant), an additional class period thereby requiring the teachers to work more than half-time for one-half pay? Award at 5-6. The Agency submitted the following issues: 1. Is the issue an appropriate matter for a national level grievance under the negotiated agreement? 2. If so, was the grievance timely filed? 3. If so, was the assignment of (the grievant) to teach four periods outside of management's authorization or otherwise improper? 4. If so, what relief, if any, is appropriate under the negotiated contract? Award at 6. As to its first two issues, the Agency argued that: (1) it was inappropriate for the Union to file a national level grievance because the grievance involved individual and local issues; (2) the grievance was untimely under the parties' agreement; and (3) the Union's failure to arbitrate an earlier similar grievance precluded it from processing this grievance. The Arbitrator rejected the Agency's procedural arguments and found that the grievance was timely filed and arbitrable. Award at 15-20. As to the merits of the dispute, the Arbitrator found that the parties' different formulations of the issue were "largely differences in form rather than substance" and that both focused on the question of the right of management to assign the grievant an additional class period without a corresponding increase in pay. The Arbitrator expressed the issue as whether the assignment of the grievant to teach four class periods was beyond the scope of management's authority or otherwise improper under the parties' negotiated agreement, or applicable law or regulations. Award at 20. On the merits, the Union made two basic contentions before the Arbitrator. First, the Union contended that the Agency's decision to increase the number of class periods that half-time teachers would be required to teach changed an established past practice of requiring half-time teachers to teach only three class periods per instructional day. Award at 24. The Union maintained, therefore, that because a teacher's duty hours and class load are within the definition of "conditions of employment," the Agency was obligated under the parties' agreement to give notice to and bargain with the Union prior to changing the grievant's schedule. The Arbitrator found that the grievant's new duty day was less than half of a full-time teacher's duty day and only 5 minutes longer than the day she was required to work under her original schedule. Award at 23. The Arbitrator concluded that the change in the grievant's schedule did not constitute a violation of an established past practice or a significant change in a condition of employment. Rather, the Arbitrator found that the change was a proper exercise of management's rights under section 7106 of the Statute and, therefore, that the Agency was not obligated to provide the Union with an opportunity to bargain under the parties' agreement. Award at 25-26. The Union contended that the Agency's part-time pay policies and practices were not in accordance with the Overseas Teachers Pay Act, 20 U.S.C. 901-907 (the Act). Award at 26. In support of this contention, the Union made four arguments. First, the Union argued that the Act requires that the basic rate of compensation for overseas teachers must be equal to that of similarly situated Stateside teachers. Award at 26; Union Post - Hearing Brief at 16-17. The Agency argued that its pay policies were fully justified and in concert with the Act and that no changes should be made in its policy unless the equivalency standard was shown to be violated by means of a proper Wage Fixing Authority (WFA) survey of stateside practices. Award at 27. The Arbitrator determined, based on March v. United States, 506 f.2d 1306 (D.C. Cir. 1974), that the salary and pay practices for overseas teachers must be equivalent to their Stateside counterparts. Award at 27. Second, the Union argued that the Agency had not met its burden of proof to establish that its part-time pay policies and practices conformed to Stateside standards. Award at 26; Union Post - Hearing Brief at 17-19. The Agency argued that its policy of paying all part-time teachers at one-half of the corresponding rate of full-time teachers regardless of the teaching load or the hours required of the part-time teachers was consistent with law and regulation. Union Post - Hearing Brief at 17-18. The Agency argued that its practice was in accordance with section 902 of the Act, the Department of Defense (DOD) implementing regulation, DOD Directive 1400.13.21, and a Department of Defense Dependents Schools (DODDS) Wage Fixing Authority report in that only two categories of teachers (full-time and part-time) and two rates of pay (full pay and half pay) are set forth. Union Post - Hearing Brief at 18. The Union pointed out to the Arbitrator that the WFA report relied on by the Agency applied to half-time substitute teachers and not to permanent part-time teachers, Union Post - Hearing Brief at 18 n.23, and was, therefore, not an accurate reflection of the Stateside practice regarding part-time teachers in the grievant's situation. Union Post - Hearing Brief at 19. In resolving the Union's second argument, the Arbitrator determined that it would be unreasonable and unfair to conclude that the Agency had failed to meet its burden of proof that its part-time pay policy conformed to Stateside standards. Award at 27. The Arbitrator reasoned that since the grievant's duty day did not exceed one-half of the hours worked by a full-time teacher, the Agency had "properly relied upon the information it extrapolated from DOD and WFA guidelines" in setting the rate of her pay at one-half of that of a full-time teacher based on the number of hours she worked. Award at 27. However, the Arbitrator distinguished the question of whether the grievant was entitled to additional pay for the number of hours in her duty day from the question of whether she was entitled to additional pay for the increase in her duties, specifically the number of classes she was required to teach. Award at 27 and 29. As to the latter issue, the Arbitrator found that the information relied on by the Agency did not answer the question of the rate of pay due the grievant based on the number of classes taught because "no precise standard existed to govern the issue at the time it arose." Award at 27. Third, the Union argued that it had conducted an independent survey covering each of the WFA survey school districts to determine the prevailing practice regarding rates of pay and working hours of Stateside part-time teachers. Award at 26. The Union contended that its survey established that Stateside part-time teachers who worked more than one-half of the instructional day received more than one-half pay of a full-time teacher. Union Post - Hearing Brief at 20. Therefore, the Union argued that the Agency's pay policies and practices were in violation of the Act because they were inconsistent with the prevailing Stateside standards. The Arbitrator determined that the results of the Union's survey were neither persuasive nor dispositive because, among other things, it did not address the issue present in this case, that is, the pay policy for part-time teachers whose duty day was less than one-half of a full-time teacher's duty day but who were required to teach two-thirds of the total class periods in the instructional day. Award at 28. Fourth, the Union argued that the grievant's duty assignment and rates of pay were not fair, reasonable, or equitable and were in conflict with the prevailing Stateside practice. Award at 26, 29; Union Post - Hearing Brief at 22-25. Specifically, the Union argued that the Agency had conceded that a class load of four instructional periods should be compensated at two-thirds the rate of pay of a full-time teacher. Union Post - Hearing Brief at 25. In resolving the Union's argument that the grievant should receive additional compensation for teaching two-thirds of the classes in the instructional day, the Arbitrator found that neither the parties' agreement nor the applicable laws and regulations offered definitive guidance. Award at 29. He noted that without such guidance he was left to speculate with regard to the resolution of the issue of whether the grievant should receive additional compensation for teaching four class periods. Award at 29. The Arbitrator concluded that since there were no precise standards in the agreement, law, regulation or WFA schedules, there was no basis on which he could decide the pay dispute. He further determined that the dispute could be resolved consistent with the parties' agreement, law and regulations by the parties initiating a WFA survey addressing the issue. In reaching this determination, the Arbitrator noted that the Agency had indicated in its post-hearing brief that the parties had agreed to initiate a WFA survey to determine the rates of pay for part-time teachers in Stateside schools. As his award, the Arbitrator directed the parties "to initiate the necessary action through the offices of the WFA to survey (S)tateside schools for the purpose of ascertaining the pay policies and practices with regard to the matter of compensation for part-time teachers whose duty time is less than one-half of that of a full-time teacher, but whose class assignments are greater than one-half of those of a full-time teacher." Award at 33. He also directed that the results of the survey were to be applied retroactively to the grievant and he retained jurisdiction to resolve any disputes which arose over (1) the formulation or implementation of the survey or (2) its application to the grievant. The Arbitrator also ruled that one of the Union's witnesses at the arbitration hearing was entitled to official time and reimbursement for travel expenses and denied the Union's request for attorney fees. IV. First Exception A. Contentions The Agency contends that the Arbitrator's award is contrary to law. In support of this contention, the Agency asserts that the Arbitrator concluded that overseas teachers' pay at all levels and at all times must be the mirror image of U.S. teachers' pay. The Agency argues that in interpreting section 902 of the Overseas Teachers Pay Act, the court in March did not mandate that overseas teachers' salaries were to be exactly equal to Stateside teachers' salaries and did not address procedures for changing pay policy. The Agency further argues that DOD has broad discretionary authority under the Act to regulate the compensation of teachers. The Agency relies on a decision of the Comptroller General in E. Kay Weger and Martha Wilson, Comp. Gen. No. B-223389 (Sept. 19, 1986) (unpublished), as substantiating the authority of DOD to establish pay schedules of overseas teachers. The Agency also maintains that the parties and the WFA had agreed on a procedure for effecting pay policy changes and such changes had always been prospective. The Agency acknowledges that the procedure is not mandated by the Act or the court's decision in March, but argues that precipitous policy changes cause administrative burdens and do not meet the intent of the Act. B. Analysis and Conclusion We find that the Agency has failed to establish that the Arbitrator's award is contrary to the Overseas Teachers Pay Act. However, for the reasons stated below, the award must be modified to provide that the results of any WFA survey are to be applied to the grievant prospectively. Contrary to the Agency's argument, the Arbitrator did not find that the pay of overseas teachers had to be the mirror image of the pay of U.S. teachers at all levels and at all times. The Arbitrator found that under section 902(a)(2) of the Act, the WFA must fix the basic compensation for teachers at rates equal to the average rates of compensation for similar positions of a comparable level in urban school districts in the United States. Award at 21. That is the language of the statutory provision. The Arbitrator's further finding that the salary and pay practices for overseas teachers must be equivalent to that of their Stateside counterparts and his interpretation of the court's decision in March, Award at 26-27, are consistent with the Act and the court's decision. As the Agency acknowledges in its exception, the Act expressly entitles overseas teachers to receive salaries "equal to" the "average" of those of the defined class of teachers. 20 U.S.C. 903(c); March at 1313. The court in March further held that the clear purpose of the Act, as amended, was to guarantee overseas teachers the same salaries they would receive for performing the same duties in Stateside schools. Id.; Department of Defense Dependents Schools and Overseas Education Association, 13 FLRA 475, 477 (1983). We note that the court in March specifically found that the daily rate paid to overseas teachers is an integral part of their "basic compensation" and that Congress intended the statutory equality mandate to apply to all elements of teachers' basic compensation in order to put them on a par with their Stateside counterparts. March at 1319. Therefore, the Agency has not substantiated its assertion that the Arbitrator's interpretation of the Overseas Teachers Pay Act and the decision in March are contrary to law. The Agency also has not substantiated its claim that the Arbitrator's findings concerning the pay entitlement of overseas teachers interferes with DOD's discretionary authority to regulate compensation for those teachers. The Arbitrator found that the Agency had "acted in good faith and in accordance with the best authority available to it at the time" in paying the grievant one-half of a full-time teacher's salary based on the number of hours she worked. Award at 27. However, as indicated above, the Arbitrator was not persuaded by the evidence submitted by the parties in support of their respective positions with regard to the compensation due the grievant based on the number of classes she taught. He found that there were no precise standards in the parties' agreement, law, regulation or WFA schedules to govern disposition of the issue of the appropriate compensation for a teacher in the grievant's employment situation, that is, teaching less than one-half of the hours required of a full-time teacher but teaching two-thirds of the class load of a full-time teacher. Therefore, because of the absence of persuasive evidence and dispositive authority, the Arbitrator concluded that he was unable to determine whether the grievant was being properly paid in accordance with comparable Stateside practice based on the number of classes she was required to teach. Such a finding does not in any way interfere with the Agency's discretion. Rather, such a finding merely confirms the statutory mandate, as recognized by the courts and the Authority, that overseas teachers must receive salaries equal to the average salaries of similarly situated Stateside teachers. As noted, the Agency relies on the decision of the Comptroller General in E. Kay Weger in support of its position. In his decision, the Comptroller General recognized that DOD's policy was that "the pay of part-time teaching positions be fixed at one-half the rate of corresponding full-time positions. . . ." The Comptroller General found that there was nothing in the record in the dispute before him "to demonstrate that this policy has caused the basic compensation of part-time DOD teaching positions to be fixed at rates which are not equal to the average range of rates for similar part-time positions that may exist in urban school districts in the United States. Hence, we have no basis for concluding that this policy is prohibited by statute or is otherwise invalid." The Comptroller General determined that since the claimants in the dispute had been paid in accordance with the DOD policy and the terms of their employment agreements, he was unable to conclude that they were underpaid or entitled to backpay. He therefore denied their claims. The Arbitrator's conclusion in the case before us that he was unable to determine on the record before him whether or not the grievant was properly paid under the Overseas Teachers Pay Act based on the number of classes she was required to teach and that a WFA survey would serve to resolve the question is not inconsistent with the Comptroller General's findings and conclusions, which were based on the record in that matter. The Arbitrator did not find that the Agency's pay policy as applied to the grievant was contrary to law or otherwise invalid. Rather, like the Comptroller General, he concluded that there was no basis in the record before him on which he could make a finding that the grievant was improperly paid. However, unlike the Comptroller General, he determined that more information was necessary to decide the dispute rather than denying the grievant's claim. We find nothing in the Comptroller General's decision that would have required the Arbitrator to deny the grievance. Thus, merely because the Comptroller General found, based on the facts and circumstances in the E. Kay Weger case, that he was unable to conclude that the employees were underpaid, does not establish that the Arbitrator in this case erred as a matter of law in finding, based on the facts and circumstances before him, that he was unable to decide whether the grievant was properly paid. Additionally, unlike the claimants in the dispute before the Comptroller General, who had been informed in advance of their employment that they would be required to teach four class periods in a seven-class instructional day, the grievant in the case before us taught a three-class schedule for 2 school years before being changed to a four-class schedule. Thus, the employment agreements of the claimants in the case before the Comptroller General and that of the grievant in this case are distinguishable. Furthermore, the Comptroller General's finding that the Agency's policy of paying part-time teachers one-half of the compensation of full-time teachers regardless of the number of hours or classes taught was not prohibited by the Overseas Teachers Pay Act does not mean that the Comptroller General found that the disputed policy is mandated by the Act. The congressional mandate is that overseas teachers must be paid at a rate equal to the average rate of pay of similarly situated Stateside teachers. The Comptroller General's decision does not preclude the Agency from exercising its discretion under the Act by another policy, for example, a policy of paying part-time teachers based on the number of classes taught, as long as the policy results in the teachers being paid at a rate equivalent to that of similarly situated Stateside teachers. Therefore, we conclude that the Comptroller General's resolution of the specific claims before him in E. Kay Weger is not dispositive of this dispute. In his award, the Arbitrator directed that the results of the WFA survey were to be applied retroactively to the grievant. In order for an award of backpay to be authorized under the Back Pay Act, 5 U.S.C. 5596, an arbitrator must determine that the aggrieved employee was affected by an unwarranted or unjustified personnel action and that such unwarranted action directly resulted in the withdrawal or reduction in the pay, allowances, or differentials that the employee would have otherwise received. For example, Social Security Administration and Local 1760, American Federation of Government Employees, AFL - CIO, 17 FLRA 1063, 1064 (1985). In this case, the Arbitrator did not find that the grievant was affected by an unwarranted or unjustified personnel action which directly resulted in a loss of pay the grievant otherwise would have received. The Arbitrator found that there was no basis on the submissions before him on which he could decide the dispute as to whether the grievant was entitled to more pay because of the increase in the number of classes she was required to teach. Therefore, the Arbitrator did not make the findings necessary to support an award of backpay and his award directing the Agency to apply the results of the WFA survey to the grievant retroactively is deficient. Accordingly, we will modify the award to provide that any WFA survey results be applied prospectively. The Agency's first exception is denied. However, the award must be modified to provide that the results of the WFA survey are to be applied to the grievant prospectively. V. Second Exception A. Contentions The Agency contends that the portion of the Arbitrator's award concerning the hours in the grievant's duty day and the number of classes she was assigned to teach is contrary to management's right to assign work under section 7106 of the Statute. The Agency asserts that allowing the Arbitrator to rule on the appropriateness of assigning the grievant four classes in her prescribed duty day allows the Arbitrator to substitute his judgment for that of management and interferes with its right to assign work. B. Analysis and Conclusion We find that the Agency's contention that the award is contrary to section 7106 of the Statute is without merit. The Arbitrator expressly found that the Agency's action in assigning the grievant to teach four class periods per instructional day was a proper exercise of management's rights under section 7106 of the statute. Award at 25. We agree. The finding does not in any way constitute an improper substitution of judgment or interference with management's exercise of its right to assign work. The Agency's second exception is denied. VI. Third Exception A. Contentions The Agency contends that the Arbitrator exceeded his authority by: (1) addressing the matter of the grievant's entitlement to additional compensation after allegedly framing the issue in the dispute solely in terms of the propriety of the Agency's assignment of the grievant to teach four class periods; (2) adding terms to the parties' collective bargaining agreement by directing the parties to initiate action to have a wage survey conducted; (3) retaining jurisdiction with respect to the formulation or implementation of the survey; and (4) relying on an ex parte communication submitted by the Union after the record in the proceeding was closed. B. Analysis and Conclusion We will discuss the Agency's contentions separately below. We conclude that the Agency has failed to establish that the Arbitrator exceeded his authority. 1. The question of the grievant's entitlement to additional compensation The Agency asserts that the Arbitrator exceeded his authority in addressing this question because the Arbitrator allegedly framed the issue in the dispute solely in terms of the propriety of the Agency's assignment of the grievant to teach four class periods. The Agency's assertion is without merit. The issue of the grievant's entitlement to additional compensation for the additional class period she was assigned to teach clearly was before the Arbitrator as part of the grievance and the issue submitted by the Union. Moreover, the Arbitrator expressly found that the issues submitted by the Union and the Agency both focused on the right of management to assign the grievant an additional class period without a corresponding increase in pay. Thus, it is clear that the question of the grievant's entitlement to additional pay was included as part of the dispute before the Arbitrator. 2. The parties' collective bargaining agreement The Agency argues that the Arbitrator added terms to the parties' agreement by directing them to initiate the necessary action to have a wage survey conducted. The Agency asserts that the Arbitrator interpreted their agreement as providing that any time the Union desires and requests a change in pay policy, the WFA will be requested to conduct a survey and that any resulting change will be retroactively applied to the date of the Union's request. We find that the Agency has misconstrued the Arbitrator's award. The Arbitrator did not rule that any time the Union requests a pay policy change the Agency must join in a request for a WFA wage survey and retroactively apply any change resulting from the survey. The Arbitrator resolved a specific grievance involving a question of the entitlement of the grievant to additional compensation. He determined that there were no precise standards in the parties' collective bargaining agreement, law or regulation on which he could resolve the pay question. He further determined that the dispute could be resolved consistent with the parties' agreement by the parties initiating a wage survey addressing the issue. We do not read those determinations as adding any terms to the parties' agreement. Rather, they simply reflect the Arbitrator's reasoning and conclusions in his attempt to resolve the question of the grievant's possible entitlement to additional compensation. We note that in another case, Veterans Administration and American Federation of Government Employees, Local 2796, 24 FLRA 47 (1986), the Authority found that the arbitrator exceeded his authority in fashioning a remedy for the grievant after concluding that the agency had not violated the parties' agreement, or applicable law or regulation. However, in that case, the arbitrator framed the issue as whether the agency's termination of the grievant was in compliance with the agreement and applicable laws and regulations. The arbitrator expressly found that the agency's decision was consistent with the agreement, law and regulation. Nevertheless, the arbitrator ordered the agency to inform the grievant of future vacancies and allow the grievant to apply. The Authority concluded that by ordering that remedial relief for the grievant the arbitrator decided and awarded a remedy concerning an issue that was not submitted to arbitration. In contrast, in this case, the grievance and issue submitted to the Arbitrator by the Union clearly included a question of the grievant's entitlement to additional compensation. Moreover, in framing the issue for resolution, the Arbitrator specifically found that the issues submitted by the parties for resolution both focused on the question of the right of management to assign the grievant an additional class period without a corresponding increase in pay. Therefore, although the Arbitrator found that assigning the grievant to teach an additional class period was a proper exercise of a management right, that finding did not resolve the entire dispute. It did not resolve the question of the compensation due the grievant for teaching the additional class period. Therefore, unlike the arbitrator in the VA case, the Arbitrator in this case did not exceed the scope of the issues as submitted by the parties and framed by him. He did not exceed his authority by directing a remedy designed to ascertain the appropriate compensation for the grievant. Moreover, it is well established that arbitrators have considerable latitude in fashioning remedies and properly may direct the parties to request action from a third party. See U.S. Immigration and Naturalization Service and American Federation of Government Employees, AFL - CIO, Local 1917, 20 FLRA 391 (1985). In this case, the Arbitrator did not order the WFA to conduct a wage survey but, rather, directed the parties "to initiate the necessary action through the offices of the WFA to survey (S)tateside schools . . . ." Award at 33. The record reflects that the parties routinely request that the WFA conduct wage surveys and that the WFA acts as the Agency's agent in surveying Stateside school districts. See Union Opposition to Exceptions, Exhibit C. Thus, the Arbitrator did not order the WFA to take any action and did not direct the parties to take any action which was outside their authority. 3. Retention of jurisdiction The Agency has not established that the Arbitrator exceeded his authority by retaining jurisdiction in the dispute. Contrary to the Agency's argument, the Arbitrator did not retain jurisdiction to determine the methodology to be used by the WFA to formulate or implement the wage survey. He retained jurisdiction only to assist the parties in the event they are unable to reach agreement on initiating the necessary action for requesting a WFA survey or agreement on application of the survey results to the grievant. The Agency has failed to establish that the retention of jurisdiction by the Arbitrator for those limited purposes is deficient. See Social Security Administration and American Federation of Government Employees, AFL - CIO, 21 FLRA 392, 393 (1986). 4. Reliance on a post-hearing communication The Agency asserts that the Arbitrator exceeded his authority by relying on an ex parte communication from the Union in fashioning his award. The disputed communication was a submission from the Union contradicting a statement in the Agency's post-hearing brief that the parties had agreed to have the WFA survey the question of how part-time teachers are paid in Stateside schools. However, the Union has established in its opposition to the Agency's exceptions that the submission was served on the Agency. Moreover, the Arbitrator expressly informed the Agency that, while he noted the Union's contradiction of the Agency's statement, he had not considered the attachments to the Union's submission. Thus, contrary to the Agency's assertion, the Arbitrator did not rely on an ex parte communication from the Union in fashioning his award. We conclude that the Agency's third exception is without merit and it is denied. VII. Decision For the reasons stated above, the Agency's exceptions are denied. However, the Arbitrator's award is modified to provide that the results of any WFA survey conducted as a consequence of the Arbitrator's award will be applied prospectively to the grievant.
