Temporary work or temporary employment refers to a situation where the employee is expected to leave the employer within a certain period of time. Temporary employees are sometimes called "contractual" or "seasonal" or "freelance" or "temps." Agricultural workers are often temporarily employed for harvesting.
In some instances, temporary professional employees (particularly in the white collar fields, such as law, engineering, and accounting) even refer to themselves as "consultants." This is not to be confused with actual consultants (such as management consultants) who are salaried employees a part of the middle management.
They may work full-time or part-time, depending on the individual case. In some instances, they are given benefits (such as health insurance), but usually the best treatment is reserved for the permanent employees.
Temporary employees are also used in work that has a cyclical nature that requires frequent adjustment of staffing levels.
