N.J. Stat. § 18A:30-9.1
Notwithstanding any law, rule or regulation to the contrary, an officer or employee of a board of education, or an agency or instrumentality thereof, who does not take vacation leave that accrues in a given year because of business demands shall be granted that accrued leave only during the next succeeding year. However, vacation leave not taken in a given year because of duties directly related to a state of emergency declared by the Governor may accumulate at the discretion of the appointing authority until, pursuant to a plan established by the officer or employee's appointing authority, the leave is used or the employee or officer is compensated for that leave, which shall not be subject to collective negotiation or collective bargaining. This provision shall apply only to officers and employees who commence service with the board of education, or the agency or instrumentality thereof, on or after the effective date of P.L. 2010, c. 3. This section shall not be construed to affect the terms in any collective negotiations agreement with a relevant provision in force on that effective date.
