N.J. Stat. § 26:3-94
No regional health commission shall appoint any person as health officer, public health laboratory technician, sanitary inspector, veterinary meat inspector or plumbing inspector nor employ a person to do work ordinarily performed by a health officer, public health laboratory technician or an inspector of any of the classes named who is not the holder of a current license issued by the State Department of Health for the performance of such type and class of work. Each person who shall have been employed as a full-time employee of a local board of health or district health board, whose employment by such agency was governed by the provisions of the Civil Service law, and whose employment by such agency shall have been terminated by reason of the assumption of its activities and responsibilities by a regional health commission, shall be transferred to the regional health commission, shall be assigned duties comparable to those previously performed by him, and shall be entitled to and credited with all rights and privileges accruing to him by reason of his tenure in such previous office or position, the same as if the entire period of such previous employment had been in the position to which he shall have been transferred. His compensation shall be fixed by the board at not less than the amount received by him during the fiscal year preceding the date he shall have been transferred to the regional health commission. Each person who shall have been employed as a full-time employee, for a period of 2 years or more, of a local board of health or a district health board, whose employment by such agency was not governed by the provisions of the Civil Service law, and whose employment by such agency shall have been terminated by reason of the assumption of its activities and responsibilities by a regional health commission, shall be transferred to the regional health commission, shall be assigned duties comparable to those previously performed by him and shall be entitled to and credited with all rights and privileges accruing to him by reason of his tenure in such previous office or position, the same as if the entire period of such previous employment had been in the position to which he shall have been transferred. His compensation shall be fixed by the board at not less than the amount received by him during the fiscal year preceding the date he shall have been transferred to the regional health commission. In the event employment by the regional health commission to which a person is transferred pursuant to this act is governed by the provisions of the Civil Service law, the regional health commission shall certify to the Civil Service Commission the entitlement of such person to those rights and privileges to which he shall be entitled and which he shall be credited pursuant to this act. In such event, the Civil Service Commission shall appropriately classify such person in the competitive civil service without examination; such person shall thereafter be subject to all the provisions of the Civil Service law with regard to the terms of his employment, promotion, tenure, classification, compensation and like matters. Every person who shall have been employed as a part-time employee of a local board of health, for a period of 2 years or more and whose employment by such agency shall have been terminated by reason of the assumption of its activities and responsibilities by a regional health commission, shall be placed on a preferential re-employment list for a period of at least 2 years for positions in the regional health commission requiring the same licensure and type and class of work.
