Another Couche-Tard convenience store has closed its doors as workers were negotiating their first collective agreement.

The dépanneur at the corner of Jean-Talon Boulevard East and Iberville Street was locked up Thursday late afternoon, hours after unionized employees enacted pressure tactics to bolster contract talks.

Cashier Luis Donis said when he showed up for his shift Thursday at 5 p.m., his manager told him he wasn't going to work.

"He said we should come into the back store, and said we had two minutes to pick up everything we had, our personal belongings, whatever, and to get out," Donis said.

The pressure tactics adopted included wearing union stickers on their uniform shirts.

According to the CSN Labour Federation, this is the second Couche-Tard outlet to close once workers decided to unionize.

A Couche-Tard at the corner of Saint-Denis and Beaubien Streets closed in April, shortly after workers received their union accreditation.

Couche-Tard operates more than 5,700 convenience stores and service stations in Canada and the United States.
