Q: When my coworker was promoted recently, a colleague congratulated her, then made a nasty comment about her appearance. My coworker was hurt and annoyed but didn’t say anything. Shouldn’t she have said something?
A: When someone is gratuituously insulting in that way, yes. Your coworker’s best approach would have been to respond to the colleague in private, remaining as calm as possible. She might have said that she didn’t appreciate the remark, and expects no further incidents of unprofessional behavior.
