There are several reasons why companies use temporary workers. First, temporary workers can be hired more quickly than full-time employees, which can be helpful when a company needs to fill a position quickly. Second, temporary workers are usually less expensive than full-time employees because they do not receive the same benefits (such as health insurance and paid vacation days). Third, temporary workers can be used to fill positions that are only needed for a short period of time, such as during a busy season or when a company is undergoing a large project. Fourth, temporary workers can be a good way for a company to test out a new employee before committing to hiring them full-time. Finally, temporary workers can provide much-needed flexibility for a company that has fluctuating staffing needs.
