I was denied applying for a promotion within my department. HR stated I could not apply while on medical leave. I was on leave under FMLA, maternity leave. They didn't let me apply and said it was because I was on medical leave. What should I do?
What you should do is go back to work. Once you are working again, you might have the opportunity to apply for a new position. Your employer is not required to give you the opportunity for a promotion you while you are on leave.
