The union representing striking support workers at Carleton University has filed a complaint with the Ontario Labour Relations Board, accusing the university's administration of unfair labour practices.

"We are calling out the university's administration for bargaining in bad faith," wrote Jacynthe Barbeau, a negotiator for CUPE 2424, in a statement released late Tuesday evening.

About 800 support staff at Carleton have been on strike since March 5 in a dispute largely to do with pension benefits.

Barbeau said school administrators are not accurately portraying the union's position or their own, making it more difficult to find a resolution.

"This type of behaviour only helps to prolong the dispute and prevent the kind of negotiations that are needed to resolve it."

University will defend itself, spokesperson says

The university has not asked to return to the bargaining table, according to the union, which also accused Carleton of suggesting otherwise.

"Our determination to keep the rights and protections around our pensions doesn't give the university's administration permission to mislead Carleton's workers or the public," Barbeau wrote in a statement.

On Wednesday, a Carleton spokesperson said the school will defend itself against the complaint and believes it will be found without merit.

"The university will continue to provide bargaining updates and stands by the accuracy of information provided to the university community," Beth Gorham wrote in an emailed statement.
