Kittery Union Police officers have filed six grievances against Captain Paul Callahan, including disputes over duty shifts, the hiring process, and work assignments. Early this month, the patrolmen and sergeants unions took a vote of "no confidence" in Callaghan, saying that they feel he is an ineffective leader. Officers feel that Callahan hasn’t come through on issues they expected him to deal with. The grievances show that in the past officers have practiced at the South Berwick Rod and Gun Club for training using their service weapons with 50 rounds of ammunition given by the department to the officers, per month. The Police Department had been paying for officers' memberships, but they say Callaghan allowed that arrangement to lapse. Callahan said without a certified weapons instructor during those sessions, the department could be looking at a potential liability.
