All U.S. military installations in the state of Rheinland-Pfalz are expected to see strikes by their German employees this week, the union representing them said Monday.

Ver.di is organizing a one-day “warning strike” Wednesday in response to stalled wage negotiations, the union said in a statement.

The strike is expected to last the entire day on Wednesday. Additionally, Ver.di’s statement urged workers scheduled for overnight shifts that begin late Tuesday or end early Thursday to strike for their entire shift.

Besides the spate of installations that make up U.S. Army Garrison Rheinland-Pfalz, the state also hosts Ramstein Air Base and Spangdahlem Air Base.

The sprawling Kaiserslautern Military Community in Rheinland-Pfalz is the largest overseas U.S. military community. It’s home to tens of thousands of U.S. service members and their families.

The most recent round of collective bargaining talks ended Feb. 24 with Ver.di employees offered a 1.7% annual raise, which the statement said was “completely inadequate.”

The union is calling for a one-time payment of 320 euros and an annual 3% salary increase for employees over a 10-month period. It is also seeking an additional pay hike for fire department employees of 2 euros per hour.

Short-duration strikes have occurred sporadically in recent years at bases in Germany. Most base services typically continue uninterrupted during the walkouts but with some delays.

The union will also hold a demonstration at Stiftsplatz in Kaiserslautern on Wednesday at 10:30 a.m.
