Union Wage Claims, CBAs, and Federal Preemption: Reyes v. Bulwark Construction
A union plasterer could not keep California wage claims in state court where resolving the claims required interpreting the collective bargaining agreement.
- California wage claims can be displaced by federal labor law when deciding the claim requires interpreting a collective bargaining agreement.
- The forum fight can matter as much as the wage claim itself because LMRA preemption can move a case away from California state-law procedures.
- Union employees and their lawyers should evaluate the CBA early, before assuming a state wage claim will stay in state court.
What Happened
The plaintiff was a union plasterer who brought California wage claims against Bulwark Construction. The employment relationship was governed by a collective bargaining agreement, which became central to the employer's argument that federal labor law displaced the state-law claims.
The dispute therefore was not just about wages. It was also about which legal system would decide the claims. If the claims required interpretation of the CBA, section 301 of the Labor Management Relations Act could preempt the state-law theory and move the dispute into a federal labor-law framework.
What the Court Decided
The court held the wage claims were preempted because resolving them required interpreting the collective bargaining agreement. That meant the claims could not proceed simply as ordinary California wage claims in the same way they might for a non-union employee.
The decision reflects the familiar LMRA distinction: a court may look at a CBA without preemption, but if the claim substantially depends on interpreting CBA terms, federal law controls.
Why It Matters
Union employees still have wage rights, but the route to enforcing them can be different. Some claims may remain independent California statutory claims. Others may depend so heavily on negotiated CBA language that federal preemption changes the forum and the procedure.
The Bottom Line
Union workers still have California wage rights, but the collective bargaining agreement can decide the forum. When a claim turns on interpreting the CBA, federal labor-law preemption can move it out of state court before the wage issue is ever reached.
