A few lost jobs and horrible bosses later I can summarize the experience as follows:
1. Bullying is legal. Unless it’s provable that it is based on one of the protected classes.
2. Because it is legal, companies side with the aggressor to deny everything and absolve themselves from liabilities.
3. Bystanders rarely help you. They may show solidarity, but will not step in on official channels.
4. Lawyers are expensive and it’s very hard to pursue any claims.
5. Documentation is very hard because modern workforce is trained on how to not get sued (unless someone is really stupid)
6. Some laws like “two party consent” for recording that is meant to protect privacy, has the unintended consequences of enabling abuse.
TLDR; harassment is legal and okay. Workers have limited protections.
