Bus cancellations and delays continue in Winnipeg as drivers continue to refuse voluntary overtime.

The tactic is part of the ongoing labour dispute with the City of Winnipeg.

City officials say 25 routes experienced disruptions during the morning commute Tuesday.

"I guess it's wait and see if it shows up,” said bus rider Wendy Boel.

Bus drivers and mechanics have voted for a strike mandate. While a strike date is not imminent, the delays to bus service has some riders saying drivers shouldn't be able to walk off the job, ever.

“I think it’s essential to a lot of people, for sure,” said bus rider Michael Kananoja.

Fire, ambulance and paramedics are not allowed to strike in Winnipeg because they're deemed essential services. Four years ago, Toronto declared transit an essential service. Mayor Brian Bowman would not touch the subject, at least not yet.

"I'll defer comment until after we've reached an agreement," said Bowman

And neither would Manitoba's labour minister.

"Well, I think that's a discussion the city needs to have with its workers," said Labour Minister Erna Braun.

Other riders said bus drivers should have the right to strike, saying you can't compare inconvenience to safety.

"I don't think it's as important as fire or police though, myself personally," said bus rider Doug Last.

Both sides are back at the bargaining table with a provincial conciliator on hand to try to break the impasse.

Riders are advised to check Winnipeg Transit’s website for schedule changes.
