Greater Dayton Regional Transit Auth. v. Amalgamated Transit Union AFL-CIO Local 1385

**What Happened:** A dispute arose between the Greater Dayton Regional Transit Authority and the Amalgamated Transit Union over work assignments. The union claimed that certain job tasks should only be performed by workers in specific job classifications, as outlined in their collective bargaining agreement and established workplace practices. When the employer disagreed, the matter went to arbitration, where an arbitrator ruled in favor of the union. The transit authority then challenged this decision in court. **What the Court Decided:** Both the trial court and appellate court sided with the union, confirming the arbitrator's award. The court found that the arbitrator's decision was properly based on the collective bargaining agreement and supported by clear past practice showing that only certain classified employees had historically performed these specific tasks. **Why This Matters for Workers:** This ruling reinforces that employers must honor both the written terms of union contracts and established workplace practices when assigning work duties. It shows that courts will uphold arbitration decisions that protect workers' job classifications and prevent employers from reassigning work to different employee groups without proper justification. For unionized workers, this strengthens the protection of negotiated work assignments and demonstrates that past practices carry legal weight in workplace disputes.
