The city of Roseville and the union representing its police force remain at odds over a contract extension.
In late May, the City Council voted 4-0 to impose its "last, best and final" offer on the 100-member unit.
The primary area of disagreement was in the city's insistence that police officers pay the full employee contribution to their pension plans, which amounts to 9 percent of their salary. That condition went into effect Saturday.
The contract changes result in a budget savings of $875,000 a year, city officials said.
Jerry Wernli, a patrol officer and unit president, said negotiations were never contentious but that the city showed little to no flexibility.
Wernli said the imposed contract will hurt morale and will drive some officers to seek employment elsewhere.
Mayor Susan Rohan said the vote was a prudent business decision.
"We could pretend and just kick the can down the road," Rohan said, "but this is a council that decided they are not going to do that anymore."
