Employees claim the company isn’t presenting them with a fair contract offer that reflects the record-breaking profits it’s seeing.

Thousand of Costco Teamsters across the U.S. are preparing to strike by the end of the month if the company does not present a "fair contract offer," the union says.

Costco Teamsters have voted to authorize a strike. The vote, passed with 85% of voters in favor, acts as a push from union members for a fair contract offer as the Costco Teamsters National Master Agreement is set to expire on Jan. 31.

Teamsters said its members voted in favor of a strike as they entered a final round of talks to reach a new contract ahead of a Jan. 31 deadline.

More than 18,000 Costco workers will be walking picket lines in less than two weeks if a labor dispute over wages and benefits is not resolved, according to the Teamsters union. Members voted by an 85% margin to authorize a strike when their current contract expires on Jan.

"Costco Teamsters vote to strike over unfair contract amid record profits " was originally created and published by Retail Insight Network, a GlobalData owned brand.

While Costco is known for paying its employees higher wages than its competitors, the union is accusing the company of not sharing its recent success with workers.

The majority vote came amid the final round of contract negotiations between Costco and the International Brotherhood of Teamsters, Reuters said.Start the day smarter. Get all the news you need in your inbox each morning.
