The union representing BC Transit employees in Greater Victoria is heading to the Labour Relations Board on Tuesday in an attempt to stop BC Transit from contracting out of bus maintenance work.

Employees are in the middle of a ban on overtime in their labour dispute with the transit authority.

"We do believe that they're in violation of the labour code by contracting this out to replacement workers,” says President of CAW local 333, Ben Williams.

But Meribeth Burton with BC Transit says there is a contracting out clause in their collective agreement that allows the company to contract out when they don't have the resources, including staff, to do the work in a timely fashion.

She says the Mechanics Department has seven vacancies.  She says right now, if there is no workers available for overtime, they can't keep up with demand.
