With their strike now in its 12th week, striking York Region Transit workers are picketing in front of at least three facilities Tuesday.

Members of Amalgamated Transit Union Local 1587 are holding up vehicles at two Miller Transit facilities – the company's Woodbine Avenue headquarters in Markham and a nearby property just south of Highway 407.

In addition to holding up Miller Transit vehicles as they attempt to exit the properties, striking workers will be handing out pro-union flyers to commuters on Woodbine Avenue.

Members of ATU Local 113 continue to picket at a Veolia Transportation garage at Keele Street and Bowes Road.

Additional pickets may be set up at transit stations in York Region.

About 550 bus drivers and mechanics who work in two YRT divisions have been on strike since Oct. 24.

In a vote last Friday, ATU Local 1587 members rejected Miller Transit's latest contract offer. Members of ATU Local 113 will vote on Veolia Transportation's latest offer Jan. 17.

Union leaders attempted to dismiss both offers without putting them to a vote, but the Ontario Labour Relations Board ordered the union locals to present the offers to their members.

ATU Local 1587 represents about 340 workers, who are employed by Miller Transit and First Canada in YRT's southeast and north divisions.

ATU Local 113 represents 220 Veolia Transportation employees who work on Viva routes.

The strike has shut down about 60 per cent of the region's bus routes, and is affecting more than 44,000 riders every day.
