Starbucks sent an internal memo to its employees banning them from wearing accessories or clothing that shows support for the Black Lives Matter movement.

BuzzFeed News obtained the memo, which reminded staffers of the company’s accessories policy that forbids accessories that “advocated a political, religious or personal issue.” A number of employees told the outlet that the company commonly permits and even advocates that employees don pro-LGBTQ+ pins, particularly during Pride Month in June.
