Hi, do you feel comfortable telling your boss about their behavior? Because its not fair to you and its none of their business. Where I work, thats what I would do. I wouldn't feel comfortable in that situation at all. You don't have to tell the boss anything personal. I would just let them know how you are being treated, so he or she can put a stop to it. Not that you are trying to get them in trouble, but its the boss or company's job to deal with this.
