IBT reviews

My boss decided she didn't like me, accused me of being on substances while at work. I said that wasn't true. I was told I could be sent to a lab to see the last time I had alcohol or whatever else I was being accused of. I said that was fine because I was innocent. Realizing she had picked a loser in ways to get rid of me. The very next week I was given a "Counseling Statement" because I had left the office at lunch and worked from home for the rest of the day - which had until then had been acceptable. I was given things to improve upon: Not leaving the office without telling someone, doing Salesforce training modules, etc. I did 56 Salesforce training modules in a week and only worked in the office one day since the "counseling statement" and I did not leave on that day. And then the very next week, I was fired for being too quiet but the separation letter cited a harassment policy. I asked who I had harassed and was told "That's just something HR puts on there" and it didn't mean anything. TLDR: My manager decided she wanted to fire me and then went looking for a justification for it. She couldn't find a real reason so she made some stuff up and fired me with no reason. NO OTHER PERSON IN THE WHOLE COMPANY TALKED TO ME DURING THIS.
