Terrifying experience - Manager General Mills Employee Review

I used to think this is an okay company, but recent experience maybe reveal what kind of company it truly became. There is a HR unit called employee relationship, and they use threatening and coercion to force you comply and do what they want you to do. I am not a lawyer, but I guess their approach is not strictly speaking legal, I am leaving anyway and I don't have the time to fight this. (facing a corporation individual is always vulnerable I guess) and I also don't want my manager to be in trouble. So really think twice before you want to join this company.
