Worst place to work - Avis employé Research Associate Bio-Techne

Accused of dealing drugs at work because a black coworker came to get a piece of gum from my desk. My supervisor went through my desk and found vitamins (they were prenatal vitamins) and brought them to hr. I was escorted out until it was verified they were vitamins. After the supervisor made himself look bad he started saying i had performance issues. Ultimately i ended up getting fired because this supervisor made such a fool of himself to ever face me again.
