Can a New Jersey employer require a doctor's note? Generally yes, but New Jersey's Earned Sick Leave Law limits it: an employer cannot require documentation for one day, or for two consecutive days, of earned sick leave. It can require reasonable documentation only for three or more consecutive days. Otherwise it depends on your employer's policy.
New Jersey has a statewide paid-sick-leave law, the Earned Sick Leave Law, in effect since 2018. Nearly all employers, regardless of size, must let employees accrue one hour of paid sick leave for every 30 hours worked, up to 40 hours a year. The law bars employers from demanding a note for short absences and allows reasonable documentation only for three or more consecutive days. A verifiable physician's note satisfies such a request.
How sick leave works in New Jersey
New Jersey has a statewide paid-sick-leave law. The New Jersey Earned Sick Leave Law has been in effect since 2018 and covers nearly all employers regardless of size. Employees accrue at least one hour of paid earned sick leave for every 30 hours worked, up to 40 hours per benefit year, and can use it for their own or a family member’s illness, preventive care, certain school-related needs, and safety-related absences, among other covered reasons.
The state law sets a floor that applies across New Jersey and preempts conflicting local ordinances, so the same core rules apply statewide.
When a doctor’s note can be required
No New Jersey or federal law flatly forbids an employer from asking for a doctor’s note, but the Earned Sick Leave Law sets clear limits for earned sick leave. An employer cannot require documentation for a single day, or for two consecutive days, of earned sick leave. It may require reasonable documentation only when leave is used for three or more consecutive days, or on certain dates the employer has specified in advance.
For time off that isn’t earned sick leave, it’s the employer’s own policy that decides whether a note is needed. Once an absence reaches the three-day threshold the Earned Sick Leave Law sets, what the law has in mind is a dated note from a licensed physician, without the diagnosis attached.
