Hi and welcome to JA. Ray here to help you today.
I am so sorry that they are doing this to her.She can file with EEOC and claim sexual harassment.There may be gender discrimination here as well.You would have protection from being an at will employee.If they retaliate you file another EEOC complaint.
The EEOC investigates and may issue a right to sue letter.You are then able to file a civil suit and seek damages here including legal fees. The fact the employer has preexisting complaints and knowledge and ahs done nothing are all facts in her favor.I would encourage her to pursue this matter through EEOC and a lawyer as well.
Employment lawyer for her here..
From EEOC the law.
Here it is unlawful to harass a person (an applicant or employee) because of that person’s sex. Harassment can include “sexual harassment” or unwelcome sexual advances, requests for sexual favors, and other verbal or physical harassment of a sexual nature.
Harassment does not have to be of a sexual nature, however, and can include offensive remarks about a person’s sex. For example, it is illegal to harass a woman by making offensive comments about women in general.
Both victim and the harasser can be either a woman or a man, and the victim and harasser can be the same sex.
Although the law doesn’t prohibit simple teasing, offhand comments, or isolated incidents that are not very serious, harassment is illegal when it is so frequent or severe that it creates a hostile or offensive work environment or when it results in an adverse employment decision (such as the victim being fired or demoted).
The harasser can be the victim's supervisor, a supervisor in another area, a co-worker, or someone who is not an employee of the employer, such as a client or customer.
