City resident Donald S. Rickett on Monday night urged City Council members to stick to their guns in the city’s three-year contract dispute with the firefighters’s union. The 82-year-old Weldon Drive resident told council members that he’s a member of “the silent majority” who sides with the city. “Fight on,” he said during Monday’s council meeting. He believes the fire department operates on a lot of waste, insisting the city should pursue making cuts. On Monday, Councilman Stephen A. Jennings made public one of the offers that the Watertown Professional Fire Fighters Association Local 191 had proposed to the city. Union president Daniel Daugherty confirmed that the union proposed retroactive pay of a 4 percent increase in 2014 and 3.75 percent increases in both 2015 and 2016.
