I once met a lady that had an office mate install an air freshener, and then this woman was off work for 18 months and then ultimately took an early retirement because she couldn't go back to work in that same location. Due to Hipaa and FMLA she was able to continue to get paid and the school employees around her never understood why they couldn't just remove the air freshener, and maybe even install a new one, to get her back(it was bought and installed by another employee in the office). The Doc just told her she couldn't go back in the building, like it was an Anthrax air freshener or something(I think what she was telling the Doc was not quite true, based on all the stories around the office of past claims by the lady)
Interesting thing, when it was installed in the morning by the coworker, the lady multiple times throughout the day commented how lovely it smelled and apparently asked where the other person got it because she wanted to "buy her own for home"..
So while I do believe in scent issues, I think there are some that may use it as a crutch(like every personal health issue out there), and I hope that isn't the case here
