Implements recommendations of State Comptroller report on municipal sick leave, vacation leave, and supplemental payment policies; establishes certain financial penalties.

This bill implements recommendations from a State Comptroller report to standardize municipal sick leave, vacation leave, and supplemental payment policies across New Jersey. It requires municipalities to align their policies with existing laws (P.L.2007, c.92; P.L.2010, c.3), prevents collective bargaining agreements from weakening these policies, and mandates public posting of all supplemental payment policies and individual payment approvals online or through public meetings. Municipalities must also publish supporting documentation for extra payments (beyond regular wages) in local newspapers and online, with public comment periods. Noncompliant municipalities face financial penalties, including annual withholding of property tax relief aid until policies are corrected.
