The firefighters union has filed a complaint against Ocean City.
It names Mayor Rick Meehan and the city council and claims they violated the town code.
The Salisbury Daily Times reports that it follows a clash at the end of last month over the work schedule.
The paper reports that at issue is a proposal for a 12 hour shift.
Currently, firefighters are required to be on 24 hours and off 72.
There have been no further negotiations since last month missing a March 1st deadline.
