The new dress code is one of several changes Starbucks is implementing this year in an effort to get back to its “community coffeeshop roots.” In January, the coffee chain announced a number of new policies, including a new code of conduct.

Baristas at more than 50 cafes have walked off the job over new clothing policies, which they say deviate from agreements made at the bargaining table.

Starbucks' employee dress code changes that go into effect Monday "focus on simplified color options that allow our iconic green apron to shine," the coffee giant said. Why it matters: It's the latest move the Seattle-based company is making to revitalize the brand by returning to its roots.
