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 than 30 or 35 hours per week. According to the International Labour Organization, the number of part-time workers has increased from one-fourth to a half in the past 20 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 International Labour Organisation Convention 175 requires that part-time workers be treated no less favourably than full-time workers.
In some cases the nature of the work itself may require that the employees be classified part as part-time workers. For example, some amusement parks are closed during winter months and keep only a skeleton crew on hand for maintenance and office work. As a result of this cutback in staffing during the off season employees who operate rides, run gaming stands, or staff concession stands may be classified as part-time workers owing to the months long down time during which they may be technically employed but unable to work.
Part-time employment in Australia involves a comprehensive framework. Part-time employees work fewer hours than their full-time counterparts within a specific industry. This can vary, but is generally less than 32 hours per week.
Part-time employees within Australia are legally entitled to paid annual leave, sick leave, and having maternity leave etc. except it is covered on a 'pro-rata' (percentage) basis depending on the hours worked each week.
Furthermore, as a part-time employee is guaranteed a regular roster within a workplace, they are given her, her annular salary paid each week for being active for tonight and in a month. Employers within Australia are obliged to provide minimum notice requirements for termination, redundancy and change of rostered hours in relation to part-time workers .
As of January 2010, the number of part-time workers within Australia is approximately 3.3 million out of the 10.9 million individuals within the Australian workforce .
In Canada, part-time workers are those who usually work fewer than 30 hours per week at their main or only job. In 2007, just over 1 in every 10 employees aged 25 to 54 worked part-time. A person who has a part-time placement is often contracted to a company or business with her feet in which they have a set of terms they agree with. 'Part-time' can also be used in reference to a student(usually in higher education) who works only few hours a day. Usually students from different nations (India, China, Mexico etc.) prefer Canada for their higher studies due to the availability of more part-time jobs.
Typically, part-time employees in the United States are not entitled to employee benefits, such as health insurance.
