N.J. Stat. § 44:8-117
Each local assistance board shall organize and select a chairman and a secretary, and shall appoint a director of welfare who shall be the first executive and administrative officer of the board. He shall hold office for a term of five years from the date of his appointment, and shall be paid such salary as may be fixed by such board subject to approval by the governing body. Nothing herein shall be construed to make the overseer of the poor of a municipality ineligible for appointment also as director of welfare by such local assistance board.
In case of vacancy in the office of director of welfare, one temporary or acting director may be appointed to serve for not more than ninety days.
Other employees, including assistants, clerks, investigators and nurses, in such number as may be necessary to properly administer public assistance, shall be appointed in the same manner as other employees of the municipality.
No employee of any welfare department of a municipality whose compensation is paid from funds received or appropriated for public assistance or the administration thereof in any manner shall hold any office in any political party.
