Oasis11- Sometimes a company will want to hire a contractor for an indefinite amount of time, but not offer a permanent position to the person.
Usually these jobs are billed by the hour and there are not a placement fee, nor are there a fee paid by the employee. Sometimes the placement firm might even allow the company to have the contractor work on a trial basis and not charge for the first few days.
This is usually done for long- term contracts where the client is unsure, or they’re may be many options for the client. In order to entice the client to take on this contractor, a staffing firm will use this tactic to get their person in.
