The firefighters are petitioning the Panama City Public Employees Relations Commission to revoke the Bay County Professional Firefighters of Panama City Local # 3216 certification as their exclusive bargaining agent.
The firefighters filed the petition Monday. It does not say why they are unhappy with the current arrangement.
At least 30 percent of the group had to sign the petition before PERC will set a hearing and an election. The hearing has been set for August 25.
This is the second time in the last four years that PERC has received a petition to revoke the local's certification. That attempt eventually failed.
Panama City firefighters are the only municipal employees group that is unionized.
