Workers at Real Canadian Superstore and Liquorstore locations across Alberta could be headed for the picket line.
With contract negotiations between the United Food and Commercial Workers Local 401 and parent-company Loblaw stalled, the union has been conducting strike votes.
In Calgary and Edmonton, 97 per cent of the secret ballots cast were in favour of going off the job.
According to the union, the company has been cutting back workers’ hours in a bid to save money on high wages.
Workers are frustrated, said union president Doug O'Halloran.
"If you go into a Superstore, it's very hard to find a unionized member on the floor to assist you. And, you know, they're overworked, they're over stressed, the company is demanding more and more with less time and the workers have just had enough of it."
The union is still waiting on strike votes in Medicine Hat, Lethbridge, Red Deer, Camrose, Lloydminster and Fort McMurray.
