Section 133 of Chapter 41 of the General Laws, as appearing in the 2010 Official Edition, is hereby amended by striking out subsection (b) and inserting in place thereof the following subsection:-

(b) Appointment of members of a police department that are not covered by the provisions of Chapter 31 of the General Laws, the Civil Service law, subsequent to the initial appointment shall be made annually or for a term of years as the appointing authority shall determine, or for an unspecified or indefinite term of appointment as long as the officer is not removed as described in this paragraph, notwithstanding the provisions of Chapter 41 of the General Laws, sections 96, 97 or 97A, or any municipal charter, ordinance or by-law. The appointing authority may remove any such officer for cause, or whatever standard is contained in any applicable collective bargaining agreement or employment contract, and after a hearing, at any time during such appointment. For police officers covered by collective bargaining agreements or employment contracts which contain standards for the discharge, termination or removal of employees, the non-reappointment of a police officer serving under an appointment subsequent to an initial appointment shall be considered to be a discharge, termination or removal and the standards shall be enforceable with respect to such non-reappointment by the procedures set forth in the collective bargaining agreement or employment contract.
