Niles City Council Monday night approved four-year contracts with four labor groups represented by United Steelworkers Local 13729.

The final four labor agreements, effective with the start of the fiscal year Oct. 1 through Sept. 30, 2016, are similar to pacts approved Sept. 10 with police and fire and cover the utilities department’s wastewater treatment plant employees, field crews and office workers and public works department street and cemetery crews.

Contracts generally continue a pay freeze. The health care coverage share shouldered increases from 5 percent to 10, 14, 18 and 20 percent over the four years.

Wage re-openers are possible in 2014, but only if the economy changes and Niles revenues rebound.

“Line workers did get a raise,” City Administrator Ric Huff said Tuesday.

“Fifty-five cents per hour the first year, 35 cents per hour each of the next three years. They were considerably below the average for that specialty.”

Huff said some minor adjustments were made to how vacation is earned.
