Starting Friday, Saskatoon bus drivers will no longer be working overtime as members of the Saskatoon transit union, Amalgamated Transit Union Local 615 (ATU), look for a new collective bargaining agreement.

“The City has officially been served noticed. As of Friday we will not be working any overtime,” said Jim Yakubowski, vice president of ATU 615.

Meanwhile, Judy Schlecht with the City of Saskatoon says the union gave the city a 48-hour strike notice. 

Schlecht wouldn't say if this means there will be any disruptions to service, but noted that drivers could legally walk off the job at 1 p.m. Friday.

The two sides have a bargaining session scheduled for Thursday morning.

On Tuesday, the union voted down the city's latest offer, a seven per cent wage increase over three years.

The union wants eight per cent over three years. They have been without a contract since late 2009.
