As a long term state employee in an exempt management position, I recently return to work from a serious health problems under FMLA. My employer resigned me to another position with a 10% cut in pay, relocated me to another office outside of my org- employment site and changes my overall duties. Question, can my employer under FMLA legally do this and what are my options?
