I was working at a production company, and I am a Sabbath-observant Jew with food allergies. There were many problematic instances at this company.
I was told I received less of a bonus than my colleagues not because of my work product, but because I took more (unpaid) time off for my sickness and religious observance. I was often forced to work in my car or in the parking lot because of exposure to airborne allergens, which my employer knew about. On multiple occasions, my direct supervisor would force me to stay in his office while he ate foods I was allergic to, resulting in a reaction, even after I asked if he could pause eating during the meetings or meet in a room without food.
I was regularly bullied privately and publicly about both issues.
