In plain language

Everything in a layoff turns on this figure, and it is computed two different ways. For most employees seniority is total continuous permanent service in the jurisdiction, regardless of title, counted in calendar years, months and days without regard to work week, work year or part-time status. For police and fire titles, in State and local service alike, it is instead service in the current permanent title plus any title that has or would have had lateral or demotional rights to that title, so time in unrelated titles does not count at all. A police title is any law enforcement rank whose entry level employees must complete a police training course; a fire title is any uniform fire department rank. Voluntary furloughs, all paid leave including sick leave injury, and unpaid leave for military, educational, personal sick, disability and family reasons are not deducted. Suspensions, other unpaid leave and time spent laid off are. Ties run through an eleven-step list headed by disabled veteran, then veteran, then the higher performance rating.

How your seniority is calculated

There are two seniority rules in this section, not one, and which applies to you decides everything that follows. For most employees seniority is the amount of continuous permanent service in the jurisdiction, regardless of title: a clerk who has moved through four different titles in the same county carries all of it. For police and fire titles in both State and local service, seniority is continuous permanent service in your current permanent title plus other titles that have, or would have had, lateral or demotional rights to it. Service in unrelated titles does not count. A police title means any law enforcement rank or title whose entry level employees must complete a Police Training Act course; a fire title means any uniform fire department rank or title. Under either rule, seniority is total calendar years, months and days, regardless of work week, work year or part-time status, so a long-serving part-time employee is not discounted for it.

What does not come off is listed and worth knowing. Voluntary furloughs, all leaves with pay including sick leave injury, and leaves without pay for military, educational, gubernatorial appointment, unclassified appointment, personal sick, disability, family, furlough extension and voluntary alternative to layoff purposes are all left alone. In State service, time in the Senior Executive Service counts provided you held permanent service before the appointment; in local service, leave to fill elective public office counts. What is deducted: suspensions, any other leave of absence without pay, and any period spent laid off, though the State deductions reach back only to 1 March 1987 and the local ones only to 1 July 1988. Somebody reappointed from a special reemployment list is treated as having continuous service, but the elapsed time between layoff and reappointment is subtracted.

Serving somewhere other than your permanent title does not freeze the clock. Employees in a working test period earn seniority from the date of regular appointment, and a permanent employee serving a working test period in another title keeps accruing in the permanent title as well. The same holds for permanent employees serving provisionally, temporarily or on an interim basis. Service accumulated before an intergovernmental transfer counts as service in the new jurisdiction, unless a police officer waived accumulated sick leave and seniority rights to make the move.

Preferred status is a separate lever, and it outranks length of service. It means a higher ranking for layoff purposes than anybody currently serving in a demotional title, and it goes to permanent employees who exercise demotional rights in a layoff other than to a previously held title, and to employees reappointed from a special reemployment list to a lower title in the same layoff unit. Where more than one person has it, priority turns on the class code of the title they were laid off or demoted from and the seniority they held in the higher title.

Ties are broken by an eleven-step sequence, and it starts with veterans status: a disabled veteran outranks a veteran, and a veteran outranks a non-veteran. Then the higher performance rating, provided everybody tied was rated by the same supervisor on the same scale, which in local service means an evaluation system the Chairperson has approved. Then service in the current permanent title and titles with lateral or demotional rights to it, then seniority in the title before a break in service, then non-continuous permanent service regardless of title, then rank on the same eligible list, then continuous provisional, temporary or interim service in the title, then total service of any kind, then two more performance rating comparisons covering the 12 months before the layoff and the 12 months before that. For police and fire titles the fifth step changes: it gives priority to the employee with greater continuous permanent service regardless of title.

The eleventh step is other factors as may be determined by the Chairperson, so the sequence does not guarantee a resolution, and a claim that seniority was worked out incorrectly is a determination of rights appeal, decided on the written record within 20 days of the final notice.

Written by the NJ Civil Service Navigator editorial team. Every statement here traces to the rules cited on this page. It is not legal advice, and a collective agreement may change how these rules apply to you.

(a) Seniority for purposes of this chapter, except for police and fire titles as set forth in (b) below, is the amount of continuous permanent service in the jurisdiction, regardless of title. An employee's continuous permanent service accumulated prior to an intergovernmental transfer effected in accordance with N.J.A.C. 4A:4-7.1A shall be considered as continuous permanent service in the jurisdiction. Seniority shall be based on total calendar years, months, and days in continuous permanent service regardless of work week, work year, or part-time status. #

1. A resignation/new appointment pursuant to N.J.A.C. 4A:4-7.9 shall not be considered a break in continuous service. #

(b) For police and fire titles in State and local service, seniority for purposes of this chapter is the amount of continuous permanent service in an employee's current permanent title and other titles that have (or would have had) lateral or demotional rights to the current permanent title. A police officer's continuous permanent service accumulated prior to an intergovernmental transfer effected in accordance with N.J.A.C. 4A:4-7.1A, shall be considered as continuous permanent service in the jurisdiction unless the police officer waives all accumulated sick leave and seniority rights in effecting the transfer. Seniority shall be based on total calendar years, months, and days in title regardless of work week, work year, or part-time status. #

1. A police title is any law enforcement rank or title where entry level employees are required by N.J.S.A. 52:17B-66 et seq. (Police Training Act) to complete a police training course. #

2. A fire title is any uniform fire department rank or title. #

3. If two or more employees in a police or fire title have equal seniority, the tie shall be broken in the order of priority set forth in (h) below, except that the fifth tie-breaking factor shall give priority to the employee with greater continuous permanent service, regardless of title. #

4. A county or municipal appointing authority may elect to provide, through adoption of an ordinance or resolution, as appropriate, that employees in police and fire titles may exercise previously held demotional rights, pursuant to N.J.A.C. 4A:8-2.2(f) against employees in any layoff unit in the jurisdiction. Such ordinance or resolution shall not be given effect during a layoff unless adopted at least 90 days prior to submission of the layoff plan (see N.J.A.C. 4A:8-1.4). #

(c) Preferred status, which means a higher ranking for layoff rights purposes than anyone currently serving in a demotional title, shall be provided as follows: #

1. Employees with permanent status who exercise their demotional rights in a layoff action, other than to a previously held title pursuant to N.J.A.C. 4A:8-2.2(f), will have preferred status. #

2. Employees reappointed from a special reemployment list to a lower title in the same layoff unit from which they were laid off or demoted will have preferred status. Records of preferred status shall be maintained by the appointing authority in a manner acceptable to the Chairperson of the Civil Service Commission or designee. #

3. If more than one employee has preferred status, priority will be determined on the basis of the class code of the permanent title from which each employee was laid off or demoted and the seniority held in the higher title. #

(d) The following shall not be deducted from seniority calculations: #

1. Voluntary furloughs; #

2. All leaves with pay including sick leave injury (SLI); #

3. Leaves without pay for the following purposes: military, educational, gubernatorial appointment, unclassified appointment, personal sick, disability, family, furlough extension, and voluntary alternative to layoff; #

4. In State service, employment in the Senior Executive Service (SES), provided the employee had permanent service prior to the SES appointment; and #

5. In local service, leave to fill elective public office. #

(e) Suspensions, other leaves of absence without pay, and any period an employee is laid off shall be deducted in calculating seniority. In State service, deductions will be made only for such suspensions, leaves of absence, and periods of layoff that began on or after March 1, 1987. In local service, deductions will be made only for such suspensions, leaves of absence, and periods of layoff that began on or after July 1, 1988. #

(f) Employees reappointed from a special reemployment list shall be considered as having continuous service for seniority purposes; however, the elapsed time between the layoff and reappointment shall be deducted from the employee's seniority. #

(g) Employees serving in their working test period shall be granted seniority based on the length of service following regular appointment. Permanent employees serving in a working test period in another title shall also continue to accrue seniority in their permanent titles. Permanent employees serving in a provisional, temporary, or interim appointment shall continue to accrue seniority in their permanent titles. #

(h) Tie-breakers based on service shall include service accumulated prior to an intergovernmental transfer effected in accordance with N.J.A.C. 4A:4-7.1A, except for all firefighters, and except where a law enforcement officer, including a sheriff's officer and a county correction officer, waives all accumulated seniority rights in the intergovernmental transfer. If two or more employees have equal seniority, the tie shall be broken in the following order of priority: #

1. A disabled veteran shall have priority over a veteran. A veteran shall have priority over a non-veteran (see N.J.A.C. 4A:5-1); #

2. The employee with the higher performance rating shall have priority over an employee with a lower rating, provided that all tied employees were rated by the same supervisor and were subject to the same PAR rating scale. In local service, the performance rating system must have been approved by the Chairperson of the Civil Service Commission or designee; #

3. The employee with the greater amount of continuous permanent service in the employee's current permanent title and other titles that have (or would have had) lateral or demotional rights to the current permanent title, shall have priority. An employee appointed to a previously held title pursuant to N.J.A.C. 4A:8-2.2(f) shall have all permanent continuous service in that title aggregated for seniority purposes; #

4. The employee with the greater seniority in the title before a break in service shall have priority; #

5. The employee with greater non-continuous permanent service, regardless of title, shall have priority; #

6. The employee who ranked higher on the same eligible list for the title shall have priority; #

7. The employee with greater continuous service as a provisional, temporary, or interim appointee in the subject title shall have priority; #

8. The employee with greater total service, regardless of title or status, shall have priority; #

9. The employee with the higher performance rating during the 12-month period prior to the effective date of the layoff shall have priority over an employee with a lower rating, provided that all tied employees were rated by the same supervisor and were subject to the same PAR rating scale. In local service, the performance rating system must have been approved by the Chairperson or designee; #

10. The employee with the higher performance rating during the period between 24 months and 12 months prior to the effective date of the layoff shall have priority over an employee with a lower rating, provided that all tied employees were rated by the same supervisor and were subject to the same PAR rating scale. In local service, the performance rating system must have been approved by the Chairperson or designee; #

11. Other factors as may be determined by the Chairperson or designee. #

Decisions we have read

State v. State Supervisory Employees Association78 N.J. 54, August 2, 1978

The State and several unions fought over which of a long list of contract proposals had to be bargained, among them seniority, the handling of demoted and provisional staff, and how appointments come off a list. The Supreme Court set the boundary that still applies: a subject is open to bargaining unless a specific statute or regulation already fixes it, and once such a rule exists it overrides anything in the contract that conflicts. Where a rule sets a floor a union may bargain for better, but where it sets a ceiling, or hands the employer a choice such as picking any one of the three names certified to it, no agreement can take that away.
