I have name changed for this. We work in a small office. A new person has started and she smells awful. It is a mixture of sweat and unclean clothes. She is only young, in her 30s. She looks fine but the scent is really bad and gets worse the more the day goes on. We don't share an office but I can smell her when I pass by her office and if she comes into my office she leaves a lingering smell. Most of us have noticed. I have mentioned to the boss but nothing has been done. No HR department. Another problem is that I have migraines which are sometimes triggered by scent. This happened a couple of weeks ago, minutes after she wafted past me I got a migraine. What can we do?
