I entirely understand. It sounds like you have a really bad manager.
Being a poor manager, however, is not a crime.
It's not against the law to be a bully, be paranoid, etc.
That is not illegal harassment. It's poor management but it's not illegal. It's a toxic work environment but it does not violate any current employment laws
. Thus, you can only try to resolve the differences with HR. There is no outside legal leverage you can use to force the conditions to improve.
I know that this is not what you wanted to hear but you deserve a candid answer. I wish very much that I could offer you an answer that was more favorable to your circumstances, but the law seems to be pretty clear. Had I been able to provide an Answer which might have given you a successful outcome, it would have been my pleasure to do so.
I hope you understand.
