Hi I work at a job that it is crucial for good communication and comaradery...yet a coworker gives me the cold shoulder. This person acts like I did something personal to him, yet when I asked if I did something he says no, he is just tired. But he cuts up with every one else on the job. He was once like this with me, but it changed a couple months ago. He barely speaks to me except to order me around. I get that he is one of my supervisors, but to give me the cold shoulder and act like I don’t exist except to order me to do something... I just don’t think it’s right. Any thoughts?
