Mass. Gen. Laws ch. 112 § 5F
Any health care provider, as defined in section one of chapter one hundred and eleven, shall report to the board any person who there is reasonable basis to believe is in violation of section five, or any of the regulations of the board, except as otherwise prohibited by law.
No employer or duly authorized agent of an employer shall discharge, refuse to hire or in any other manner discriminate against an employee because the employee has made a report to the board as required under this section, or has testified or in any manner cooperated with an inquiry or proceeding pursuant to this chapter, unless the employee knowingly participated in a fraudulent proceeding. Any person claiming to be aggrieved by a violation of this section may initiate proceedings in the superior court department of the trial court for the county in which the alleged violation occurred. An employer found to have violated this paragraph shall be exclusively liable to pay to the employee lost wages, shall grant the employee suitable employment, and shall reimburse such reasonable attorney fees incurred in the protection of rights granted by this section. The court may grant whatever equitable relief it deems necessary to protect rights granted by this section. The board may, by regulation, exempt a health care provider from the reporting obligation under this section, as to a physician who is in compliance with the requirements of a mental health, drug or alcohol program satisfactory to the board, or who has successfully concluded such a program subsequent to the actions or circumstances as to which reporting would otherwise be required.
