Me. Rev. Stat. tit. 22, § 1592

A person, hospital, health care facility, firm, association, corporation or educational institution, directly or indirectly, may not discriminate against a physician, nurse or other person by refusing or withholding employment from or denying admittance, when that physician, nurse or other person refuses to perform or assist in the performance of an abortion, nor may that refusal constitute grounds for loss of any privileges or immunities to which that physician, nurse or other person would otherwise be entitled.
