The hours worked per day for a part-time job vary depending on local labor laws, but most are four to six hours each day. This results in 20 to 30 hours each week based on a five-day working week.
Part-time work is popular with people who desperately need a job yet don't have a lot of time available to work. By definition, the number of hours worked by part-time employees has to be less than full-time employees, many of whom work a minimum of seven hours per day. Part-time workers are entitled to many of the same rights as full-time employees even though they work less hours and often for less pay.
