Generally, working part time is considered working anything less than what your employer considers full time. The Bureau of Labor Statistics defines part-time status as working on average between one and 34 hours per week. In the end, it is up to the employer to decide how many hours is part time and how many would make the job a full-time position. The Department of Labor does not differentiate between the two statuses.
A part-time contract is a form of employment that carries fewer hours per week than a full-time job.They work in shifts but remain on call while off duty and during annual leave. The shifts are often rotational.Workers are considered to be part-time if they commonly work fewer than 30 or 35 hours per week.his 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.
