Hi, there: My friend's boss won't renew her appointment for the next year. She is pregnant now, and is having H1B visa. She talked to the chairman of her department, and said that her boss couldn't fire her because she is pregnant and she can do her job. But the chairman said the professor (her boss) made the decision before he knew that she is pregnant. So there is no discrimination. My question is: Is the chairman right? I mean the boss can fire their employee who is pregnant because he does not know she is pregnant? If she wants to sue her boss, is she going to win? What kind of lawyers she needs? Please, GGJJDDMM, who have this kind of experiences or know this kind of situation gives some sdvice. Thank you so very much.
