Document everything!!!! Ever glance, rude word or attitude. Be as detailed as possible and go to HR and tell them it's a toxic work environment and it's effecting your sense of well being and ability to do your job to your fullest potential and ask them what they plan to do to help you and the company function better. Don't roll over and accept this as that won't be good for your self esteem or sense of power. Look for another job while doing this but don't let these jerks steal your job or force you out. If you do, the bullies will win, and they will continue to infect the lives of other sensitive people. Avoid violence at all cost, keep your cool on the outside. HR does work for the company and not you, but if they are doing what you say, it's a toxic environment and if you have proof and can get a witness, you probably have a legal case. Good luck
