How many hours is considered part time?

Any time less than the weekly work hours for full time workers.

Although there is no law that defines the number of hours considered part time, a worker is generally considered to work part time if he/she works less than the full-time weekly load in hours. In most countries, for example, a full-time worker works for 40 hours a week, so any weekly work load less than 40 hours is considered part-time.
