In Rhode Island, it is illegal under state law for an employer to discriminate against you because of your choice to obtain a restraining order or your choice not to obtain a restraining order.
Rhode Island General Law § 12-28-10 states: "No employer, employment agency or licensing agency shall refuse to hire any applicant for employment or discharge an employee or discriminate against him or her with respect to any matter related to employment, solely by reason of his or her seeking or obtaining a protective order … or refusing to seek or obtain a protective order."
If you believe you have been a victim of this sort of discrimination, you have the right to bring a private lawsuit against the employer, asking to have your job back and/or to receive compensation for the money you lost due to the discrimination.
To do so, you will most likely need a lawyer. Some lawyers may be willing to represent you for a "contingent fee," which means that you pay the attorney nothing unless and until you win the case. Once you win, you either pay the laywer a percentage of the money that the court awards you, or the court may order the employer to pay the lawyer instead.
The following organizations may be able to help you find a lawyer willing to take your case on a contingent basis:
