In a pair of recent cases, the National Labor Relations Board has ruled against businesses who fired workers who used profanity in the workplace.

In one case, the NLRB ruled that a business shouldn’t have fired an employee even though he berated the owner to his face. In the other, the board ruled that Starbucks was wrong to fire an employee even though he used profanity and got into an altercation with a manager in front of customers.
