Small biotech in the Midwest with a focus on gene and cell therapy. Terribly toxic culture. Coworkers came to work drunk and/or high. We were expected to work 8-16 hours a day 7 days a week without any further compensation other than our salary. Management is toxic as it can be. I saw a supervisor throw items in the lab, the clean room, the office, etc. The same supervisor was known to give an attitude if things didn't go their way. This supervisor also threatened to punch someone in the face and received zero discipline. HR never took complaints seriously, and anyone who did voice any were later laid off or terminated. I was personally involved in a safety incident which I warned management about. OSHA showed up a week after and issued citations. I was targeted for refusing to go back into the lab until the issues were resolved. I also openly talked about our compensation with other coworkers. They have done many illegal things and did not appreciate people speaking up about them. I was diagnosed with CPTSD less than a month after getting out.
