Despite Costco claims it has a stable “cared-for employee base,” over 18,000 employees disagree. Costco Teamsters have voted to strike on Jan. 31.

Members of the Teamsters union have authorized a strike against Costco on February 1 unless they reach a deal with the warehouse retailer before the current contract expires 31.

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