Employment Law Questions? Ask an Employment Lawyer.
I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear that this happened.
The default position in the law is that employment is at will, which unfortunately means that an employer can reduce or change an employee's schedule at any time - or refuse to change it, or refuse to schedule them. There is no right to a shift change, and an employee who suddenly becomes unable to work the shift they were hired for can be let go. The only way there would be a cause of action here is if you had a written contract that gave you priority in choosing hours, or if there is some evidence that the supervisor is treating you this way because of your race, gender, religion, ethnicity, sexual orientation, or age (over 40). If you believe one of those might apply, please let me know.
The fact that they've filled those shifts with other employees since the request was made doesn't legally make a difference unless you can prove illegal discrimination.
