It's a single incident. Nothing wrong at all with asking you manager a question about the dress code. The ONLY thing that could be called an incident is submitting the petition.Fuji - it's not a single incident - clearly we are not reading the same thing as multiply managers and HR was involved (as well as multiple attempts to get an exception). Anyway let's agree to disagree.
(Caveated again by we only have one side of the story.)
