What is part time job? Generally who do these jobs?

A Part-time job is a form of employment that carries fewer hours per week than a full time job. Workers are considered to be part-time if they commonly work fewer than30 or35 hours per week. According to the International Labor Organization (ILO), the number of part-time workers has increased from one-fourth to a half in the past20 years in most developed countries, excluding the United States. There are many reasons for working part-time, including the desire to do so, having one's hours cut back by an employer and being unable to find a full-time job. The ILO Convention requires that part-time workers be treated no less favorably than full-time workers.
