Hoping to stop the revolving door at the Liberty Twp. Fire Department, trustees ratified a new union contract that includes 4 percent pay hikes totalling about $114,000 annually. The new three-year deal also includes step increases based on years of service. Starting pay for a firefighter/paramedic, according to the contract, is $58,099. The first step takes the pay up to $60,995 after a year, and someone on staff for seven years will be earning $70,753, not including the annual raises.Under the previous contract, which went to state fact finding because a deal couldn’t be reached, the annual raises were 2 percent. Trustee Tom Farrell said officials knew when they worked to pass a levy two years ago, they needed to address the wage issue.
