The city of Montreal is upset with what it calls pressure tactics by police officers.
The administration says police officers are giving out fewer tickets as a way to protest the provincial government's decision to revamp pension plans.
Both parties went before the Labour Relations Board on Friday in order to deal with the complaint.
Yves Francoeur, the head of the Police Brotherhood, said the city is trying to create disputes with police officers.
"We are living with a climate of confrontation, a climate of workplace conflict, which I believe is what the city wants," said Francoeur. "But I don't think it's good for workers, nor for citizens."
Michel Parent, president of the blue collar workers umbrella group, said the city is filing complaints against every group involved with the protest at city hall on June 17, which saw workers setting fires in the street.
"The unions' argument is that we protested during our break, that there was no work stoppage. The city argues that it was a wildcat strike," said Parent.
Last week the city took firefighters to the board after discovering that response times in July, August and September were 30 to 40 seconds slower than during that time in four previous years.
After a day of closed-door discussions followed by a day of public hearings, the Board ordered firefighters to do everything possible to improve response times.
