The union representing employees of Real Canadian Superstore has handed the owners a strike notice.
Employees at three Alberta outlets delivered the notice to their bosses late Thursday evening.
The United Food and Commercial Workers union rejected an offer from parent company Loblaw earlier this week that proposed separate, lower wage scales for new employees.
“We feel that it is the offer of a company that is not rational. We feel that the offer is not even legal. We are forced into a strike position,” UFCW Local 401 said on its website.
The union said its 8,500 workers will go on a province-wide strike just after midnight on Oct. 6 unless a settlement is reached.
