In New Jersey, part-time and seasonal workers must be covered by workers compensation just like full-time employees. The state sets no minimum number of hours or weeks, so even a single part-time or seasonal hire triggers the requirement.
Who this is for: New Jersey owners whose only staff are part-time, seasonal, or temporary, and who want to know if they still need workers comp. Workers comp pays medical bills and part of lost wages after a work injury.
The short version
- No hours minimum: New Jersey covers part-time and seasonal workers from the first hire.
- Seasonal counts: a summer-only or holiday-only worker triggers the same requirement.
- The only exception is casual work: jobs that come up by chance and are not regular or recurring.
- Full-time is not the line: the requirement is about being an employee, not about hours.
- Temp agency staff: workers from a staffing agency are usually covered by the agency, but confirm it.
Do part-time hours change the rule?
No. New Jersey's definition of an employee turns on performing services for pay, not on how many hours someone works. A person who works eight hours a week is as much an employee as one who works forty. There is no threshold you stay under by keeping people part-time.
| Worker type | Must be covered? | Notes |
|---|---|---|
| Part-time employee | Yes | No hours minimum in New Jersey |
| Seasonal or holiday employee | Yes | Covered for the season they work |
| Temporary hire on your payroll | Yes | Covered like any employee |
| Worker from a staffing agency | Usually by the agency | Confirm the agency carries it |
| Genuinely casual one-off helper | Often not | Must be truly by chance, not recurring |
What casual work really means
The one narrow exception is casual employment. New Jersey defines it as work whose occasion arises by chance or is purely accidental, or that is not regular, periodic, or recurring. A neighbor you pay once to help unload a delivery may be casual; a worker you bring in every weekend is not, even if the hours are few. Do not stretch this exception to cover regular part-timers.
Staffing-agency and temp workers
If you bring in workers through a staffing agency, the agency is usually the employer that carries their workers comp. That can be a clean way to staff a busy season, but you should confirm in writing that the agency covers them, because if it does not, the injured worker and the state may look to you.
A quick New Jersey example
Illustrative, not a quote. A garden center in Cherry Hill hires four seasonal workers for spring planting and no one year-round except the owner. Even though the jobs last only a few months, all four must be covered by workers comp because New Jersey has no seasonal exception. When one worker wrenches a knee loading mulch, the policy pays the treatment and part of the lost wages. Without coverage, the owner would have faced penalties starting at up to $5,000 for the first 10 days uninsured.
Real questions New Jersey owners ask
My employees only work part-time. Do I need workers comp in New Jersey?
Yes. New Jersey has no hours minimum, so part-time employees must be covered just like full-time staff. A single part-time worker triggers the requirement.
I only hire seasonal help. Are they covered?
Yes. Seasonal and holiday workers must be covered for the season they work. New Jersey does not exempt seasonal employment from the workers comp requirement.
Is there a number of hours below which I do not need coverage?
No. The requirement is about being an employee, not about hours worked. Even a few hours a week makes someone a covered employee in New Jersey.
What counts as casual work that is exempt?
Only work that comes up by chance or is not regular, periodic, or recurring. A one-time helper may be casual, but anyone you use on a regular schedule is not, even part-time.
I get workers from a staffing agency. Do I cover them?
Usually the agency carries workers comp for the people it places. Get that confirmed in writing, because if the agency does not cover them, the injured worker and the state may look to your business.
Do interns or trainees need coverage?
If they are paid to perform services, treat them as employees who must be covered. An unpaid, genuine volunteer is different, but paid interns generally count.
What is the risk of leaving part-timers off my policy?
If a part-timer is hurt and uninsured, you face penalties of up to $5,000 for the first 10 days and up to $5,000 for each 10 days after, plus paying the claim yourself and a possible stop-work order.
Why New Jersey owners choose Morrow
- We shop the right market for you. New Jersey is an open, competitive market with no state fund, so coverage comes from any of the private insurers the state authorizes, and Morrow shops several of them to fit your trade and budget instead of leaving you with one option.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
