I was placed on medical leave as a result of my pregnancy. it has been two months. In this time I have been removed from employee group messaging, removed from the call list of employees, and my locker at work has had my name removed and it appears as though I am no longer an employee. I was told I was on "medical leave" until further notice, but never given a termination notice, however I have been replaced at work. A year ago, another employee was placed on medical leave and none of this happened to him as a result of his injury, he returned and was never taken off the payroll. My only issue is that I am pregnant. do I have a discrimination case?
