One of the girls I work with pretty much wants nothing to do with me, she' said it's because I'm white. I always have the same shift as her and one other girl, and the only time she ever talks to me is when asking where the other girl is so she can talk with her, or if she needs something that she can't get from anyone else. I don't understand why skin color has to be an issue, and it makes working with her very uncomfortable and difficult. I just want to make working with her less of a problem. How can I do this?
