Transit workers in Saskatoon serve strike notice, job action could begin Sunday

SASKATOON — The union representing transit workers in Saskatoon has served the city with 48-hour strike notice.

The Amalgamated Transit Union 615 says job action could range from a complete walkout to a campaign where employees will work to rule and engage in work slowdowns and study sessions.

The union also says its members could refuse to work overtime or wear uniforms.

Service disruptions could start as early as Sunday afternoon.

Transit workers have been without a contract since 2012.

Wages and pensions have been the major sticking points in negotiations.

“We are disappointed to receive strike notice since we have been bargaining all week and have made significant progress,” said Marno McInnes, director of human resources with the city.

The city released recently numbers showing the wages its offering are close to other cities such as Regina and Winnipeg.
