How to Close a Business Legally in New Jersey

Mandatory severance, 90-day notice, and part-time workers counted — New Jersey has one of the toughest shutdown laws in the country.

Mandatory severance, 90-day notice, and part-time workers counted — New Jersey has one of the toughest shutdown laws in the country.

New Jersey’s workplace shutdown law stands out nationally for two reasons: it requires mandatory severance pay, and it counts part-time workers in its thresholds. The NJ WARN Act, significantly strengthened by amendments enacted in 2020 (effective April 2023), creates obligations that go well beyond what federal WARN or most other state WARN laws require.

For employers planning a shutdown, mass layoff, or relocation in New Jersey, the law adds a mandatory severance payment that applies regardless of whether you gave proper notice — and quadruples the penalty if you didn’t.

How the NJ WARN Act Differs from Federal WARN

The NJ WARN Act (N.J.S.A. 34:21-1 et seq.) is distinctive in several critical ways:

RegulationWhat it means for employers
Mandatory severance payNew Jersey is one of the few states requiring severance: one week of pay for each full year of service. This isn’t a penalty — it’s owed even when the employer provides full 90-day notice.
Part-time workers are countedBoth the 100-employee threshold and the 50-employee trigger include part-time workers. Under federal WARN, employees working fewer than 20 hours per week are excluded.
90 days of noticeLike New York, New Jersey requires 90 days — 30 days more than federal WARN.
Penalty severance for inadequate noticeIf you don’t give the required 90-day notice, you owe an additional four weeks of pay per affected employee on top of the standard severance.
Transfer of operations coverageThe NJ WARN Act covers situations where operations transfer to a successor employer, creating potential obligations for both the departing and incoming employer.

What Triggers the NJ WARN Act? Thresholds and Coverage

Does the NJ WARN Act Apply to My Business? (100+ Employees Including Part-Time)

The law applies to employers with 100 or more employees, counting both full-time and part-time workers. This is the same headcount threshold as federal WARN, but the inclusion of part-time workers means many employers who fall below the federal threshold are captured by NJ WARN.

Example: A restaurant group with 60 full-time employees and 45 part-time employees has 105 total workers. Under federal WARN, only the 60 full-time employees count — below the 100 threshold. Under NJ WARN, all 105 count, and the employer is covered.

What Events Trigger NJ WARN Notice and Mandatory Severance Pay?

EventThresholdNJ WARN triggered?
Plant closure50+ employees lose jobs within 30 daysYes
Mass layoff50+ employees within 30 daysYes
Transfer of operations50+ employees lose jobsYes
Layoff of 49 employeesBelow thresholdNo

How Are Employees Counted Under the NJ WARN Act?

NJ WARN counts employment losses within a 30-day period. But employers should also watch for aggregation: if layoffs over a 90-day period appear to be part of a single plan, the Department of Labor may aggregate them to determine whether the 50-employee threshold is met.

NJ WARN Act Mandatory Severance Pay: How Much and Who Qualifies

This is the provision that sets New Jersey apart from every other state except a handful.

How Much Severance Must NJ Employers Pay? (One Week per Year of Service)

When the employer provides the full 90-day advance notice:

RuleDetails
AmountOne week of pay for each full year of employment for every affected employee
CoverageApplies to both full-time and part-time workers
Calculation basisAverage weekly wages over the last three years of employment (or the duration of employment if less than three years)
Payment timingMust be paid within the regular pay cycle following the employee’s last day

Example: A warehouse worker with 8 years of service earning $800/week receives 8 weeks of severance ($6,400).

NJ WARN Penalty: 4 Extra Weeks of Severance for Inadequate Notice

If the employer fails to provide the full 90-day notice:

  • All standard severance still applies (one week per year)
  • Plus an additional four weeks of pay per affected employee
  • The four-week penalty applies regardless of how much notice was actually given

Example: The same warehouse worker receives 8 weeks of standard severance plus 4 weeks of penalty severance = 12 weeks total ($9,600).

Do Part-Time Workers Get Severance Under the NJ WARN Act?

Part-time workers receive severance calculated on their average weekly hours over the last three years. A part-time employee who averaged 20 hours per week at $15/hour for 5 years of service receives: 5 weeks × ($15 × 20 hours) = $1,500 in severance.

NJ WARN Severance Calculation Examples

EmployeeTenureAvg weekly payStandard severancePenalty severance (if under 90 days notice)Total
Full-time manager10 years$1,200$12,000 (10 weeks)$4,800 (4 weeks)$16,800
Part-time cashier3 years$450$1,350 (3 weeks)$1,800 (4 weeks)$3,150
Full-time warehouse1 year$800$800 (1 week)$3,200 (4 weeks)$4,000

Notice the pattern: for short-tenure employees, the penalty severance (4 weeks) exceeds the standard severance. A sole proprietor with 50 employees averaging 5 years of service at $700/week faces approximately $175,000 in standard severance — or $315,000 if notice falls short of 90 days.

When Must New Jersey Employers Pay Final Wages After a Layoff?

New Jersey requires final wages on the next regular payday after termination. The law is less aggressive than California’s same-day requirement but still carries penalties for late payment:

ComponentDetails
Wages and overtimeAll earned wages, overtime, and commissions must be included
Vacation payoutRequired if company policy provides for it (NJ does not mandate vacation payout by statute, but contractual and policy promises are enforceable)
Time recordsTime tracking records should be finalized through the last day to ensure accurate final pay calculations

Under the New Jersey Wage Payment Law, failure to pay final wages on time can result in penalties and the employee’s recovery of the full amount owed plus reasonable costs and attorneys’ fees.

Benefits and COBRA After a New Jersey Layoff

All benefits continue through the 90-day notice period. After termination, NJ continuation coverage extends to employers with 2–50 employees, providing up to 12 months of coverage for small group plans.

ScenarioWhat happens

Frequently Asked Questions

Does NJ WARN apply to transfers of operations?

Yes. When operations transfer to a successor employer and the transfer results in employment loss for 50+ employees, the departing employer must provide 90-day notice and severance. If the successor employer offers jobs to the affected employees within 180 days, some obligations may shift. This provision is crucial for franchise transitions, management company changes, and business sales where the physical operation continues under new ownership.

How Is NJ WARN Severance Calculated for Short-Term Employees?

The NJ WARN Act requires one week of severance per full year of employment. Employees with less than one full year of service are not entitled to standard severance — but they are still covered by the 4-week penalty severance if the employer fails to provide 90 days of notice. This means short-tenure employees can still receive significant payments when notice is deficient.

Can Existing Severance Plans Offset the NJ WARN Severance Requirement?

Yes. The NJ WARN Act allows employers to offset voluntary severance pay, separation pay, or other payments against the statutory obligation — provided the voluntary payments equal or exceed the statutory amount. If your company already offers severance exceeding one week per year of service, the statutory requirement may already be satisfied. Document the offset clearly.
