legal advice for friend

A good friend of yours has asked for some advice on workplace harassment. Your friend is a female kindergarten teacher at the local elementary school. According to her, the current principal’s practices are extraordinarily unfair and potentially discriminatory.
She shares with you that this principal often threatens teachers with a classroom grade change when they don’t agree with him. Your friend reminds you that teachers are responsible for personally purchasing everything in their classrooms other than the desks and that she has over $3,000 invested in kindergarten-specific materials. The principal has retaliated six previous times over the past 4 years, specifically against female teachers. Your friend is fearful that she will be moved at the end of the year because of her disagreement with a policy change.
