Part-Time Employee
The term "part-time employee" means a person who is employed for an average of less than 20 hours per week or a person who has been employed for less than 6 of the 12 months before the notice date. This term may include workers who would traditionally be understood as "seasonal" employees. The period to be used for calculating whether a worker has worked an average of fewer than 20 hours per week is the shorter of the actual time the worker has been employed or the most recent 90 days.
