Some Starbucks workers in the chain's largest union are objecting to the company's new dress code for baristas. Starbucks Workers United said in a post on Tuesday that baristas around the US are protesting the chain's implementation of a standard dress code this week. On April 14, Starbucks announced a standard dress code that all baristas must adhere to — a solid-color black shirt, paired with bottoms that are black, blue denim, or khaki. The union, which did not respond to a request for comment from Business Insider, told Bloomberg that walkouts have occurred at more than 50 stores. The union's website says that it represents more than 11,000 workers and more than 570 stores nationwide. As of March 30, Starbucks had more than 17,000 stores in the US. The company did not respond to a request for comment from BI. Click the link in our bio to read more about the new dress code and resulting strikes.
