In the state of New Jersey how many hours constitutes a part-time employee?

There are no legal guidelines that determine whether or not an employee is a part-time or full-time employee. A determination of whether an employee is working part-time depends on the company's policy and practice of defining employees and the hours required to be considered full-time.

The standard for full-time was typically 40 hours a week in the past, however many employers consider employees as working part time based on a different schedule i.e. under 30 hours or 35 hours a week, etc.
