You might have a claim under the Fair Labor Standards Act. There are four avenues that you can take to resolve a wage and hour concern: 1. Filing through a negotiated grievance procedure; 2. Filing through an agency's administrative process; 3. Filing with the U.S. Office of Personnel Management (OPM); or 4. Filing with an appropriate United States court.   If the following conditions apply, then a negotiation grievance procedure is your exclusive remedy: “You were a member of a bargaining unit (i.e., in a bargaining unit position), AND Your bargaining unit was covered by a collective bargaining agreement, AND Your collective bargaining agreement did not specifically exclude matters under the Fair Labor Standards Act (FLSA or Act) from the scope of the negotiated grievance procedure.”  Your ability to file in a federal court is not limited. You can file with the Federal agency that employs or employed you or the Office of Personnel Management if the following conditions apply: “You were not a member of a bargaining unit (i.e., in a bargaining unit position), or You were a member of a bargaining unit not covered by a collective bargaining agreement, or You were a member of a bargaining unit covered by a collective bargaining agreement that specifically excluded matters under the Act from the scope of the negotiated grievance procedure.” You cannot file with your Federal agency and the Office of Personnel Management at the same time.
