Metro Vancouver transit workers represented by CUPE Local 4500 have begun job action on Saturday.

More than 180 transit supervisors, engineers and a range of maintenance workers within the transit system have started refusing overtime as of 8 a.m. Saturday.

The union says the job action, which followed a 72-hour strike notice on Wednesday, comes as a last resort as talks with their employer, the Coast Mountain Bus Company (CMBC), broke down. The last collective agreement expired in October 2022.
