Is there a statue in Massachusetts that requires an employer to release an employee from their job for the day to answer a summons or subpoena

MGL c.258B s.3(l) states that "for victims or witnesses who have received a subpoena to testify, to be free from discharge or penalty or threat of discharge or penalty by his employer by reason of his attendance as a witness at a criminal proceeding. A victim or witness who notifies his employer of his subpoena to appear as a witness prior to his attendance, shall not on account of his absence from employment by reason of such witness service be subject to discharge or penalty by his employer. Any employer or agent of said employer who discharges or disciplines or continues to threaten to discharge or discipline a victim or witness because that victim or witness is subpoenaed to attend court for the purpose of giving testimony may be subject to the sanctions stated in section fourteen A of chapter two hundred and sixty-eight;"
