Warehouse workers of furniture seller Brault & Martineau have been locked out for an undetermined period following a breakdown in negotiations over pension plans, the company said.
About 220 employees of the distribution centre in Montreal East were locked out of the 7 p.m. shift on Sunday when they showed up to work.
Workers have been without a contract since Jan. 1.
A statement from the company said it offered to give future employees a modified pension plan, but maintain the current plan for present workers.
The workers' union said it will meet tomorrow morning.
