Yes, they apparently are violating her FMLA rights. If an employee properly takes FMLA leave for which she is eligible, the employer may not retaliate against her due to her use of the leave, which is a legal (federal law) right. They can move her to a different position or make adjustments to her schedule--her FMLA rights do not prevent an employer from managing its business, and management sometimes requires adjusting employee jobs, schedules, etc.--but it can't reduce her pay, demote her, cut her hours, etc. because of her use of FMLA; if it moves her to a different position, it must be a comparable one, with a closely similar salary and level (even if a different title) within the company.Your daughter may wish to contact the state or federal departments of labor and inquire into filing a complaint.
