Norwich — The City Council approved a five-year contract Monday night with Public Works Department supervisors, but unanimously rejected a second proposed contract with employee supervisors in several city departments.

The council voted 6-1 in favor of a new five-year agreement with the union representing four Public Works Department supervisors, with Alderwoman Stacy Gould voting against the contract. The pact runs from July 1, 2019, through June 30, 2024, with wage increases ranging from 2 percent to 2.5 percent per year.

The on-call stipend for three of the supervisors will increase incrementally from $1,600 to $2,400 per year over the five years, and the stipend for a foreman will rise from $750 to $1,150 over the life of the contract, city Human Resources Director Brigid Marks said.

Medical cost share for the employees will range from 10 to 12 percent per year, and the contract calls for decreasing the city’s portion of medical insurance deductibles from 60 percent to 50 percent.

A second proposed four-year contract with the 11 members of the Municipal Employees Union Independent/City Hall Supervisors was defeated unanimously Monday night.

Council President Pro Tempore Mark Bettencourt said there were proposed conditions in the contract regarding one position aldermen felt were unfair, including a two-year pay freeze for the position. He said the council asked city administrators to meet with the union and readdress the issue.

Mayor Peter Nystrom declined to comment on the vote.

Union negotiators Kathy Crees and Michael Wolak agreed with the council’s decision. Both said Tuesday the union also was not happy with the provision for the one position, but approved the draft contract believing it was the best the union could achieve for the position. Officials would not identify the position in question.

“We would concur with that,” Wolak said of the council decision. “If that’s the case, and they want to make that whole, we’re fine with that.”
