Temporary employment agencies serve a number of purposes. They can provide income for people who only prefer to work occasionally and are often privy to jobs that aren't posted anywhere else. In addition, many employers prefer to try out a potential employee on a temporary basis before hiring her full time.
Start-ups
New businesses use temporary agencies when they aren't sure how many full-time employees will be needed.
Try Outs
Employees have the opportunity to try out a company before applying for a full time position without making any firm commitment.
Movers
Temporary agencies are good sources for jobs for people who enjoy living in a variety of locations.
Sales
Students or employees changing careers can rely on the salespeople at temp agencies to sell them to the employer on a trial basis.
Diversity
Temp agencies provide a variety of job opportunities allowing employees to change industries when they need a new challenge.
Costs
Job searches can be lengthy and costly. Whereas a temp agency typically does not cost anything for employees and often can put people to work right away, providing immediate income.
