re: OT- Law Question

First question is what does her employment contract say about her hours? If it’s not in there then unfortunately your wife is out of luck. An unwritten agreement between her former director won’t prevail.

Even if that’s the case, she may have ADA or EEOC recourse. Is either your wife or your son disabled? If so, she is entitled to a “reasonable accommodation”, which could include a change in work hours. And is the other employee a different race/sex/religion/etc than your wife? And if so, can she prove she is being treated differently on that basis?
