Question: You are the HR manager for a local restaurant chain. All servers are required to wear uniforms as part of the dress code, including a large button that says "Ask Me about our Early Bird Special!" Last week, several servers started to talk about joining a labor union, and have decided to start wearing additional buttons that say "VOTE UNION!" The restaurant manager approaches you and asks you if they can require the servers to remove their union buttons in violation of the dress code. Your best advice is that: Question options: a restaurant can enforce a dress code for safety reasons, so you could ask the servers to remove the button. wearing a "VOTE UNION" button is likely protected under the NLRA. dress codes should be discouraged because they create too much legal trouble. a restaurant can enforce any dress code they choose, so long as it doesn't discriminate against religion.
