Legal Question in Discrimination Law in Michigan

There is very little that you can do with a work place "bully". The reason is that the law gives protection only to people who fall within a protected category. These categories included protection from religious discrimination, racial discrimination, people who report or are about to report a serious criminal violation to high authorities, etc. Your case falls within being treated unfairly and for that, there is no protection unless you are bound by a collective bargaining agreement. Now you understand that there is a lot greater benefit to being unionized than simply higher wages.
