You sign up for placement, and IF they have a position for you they place you there. While you are working at that position you are making MegaForce money based on a staffing contract with the client company.
Your position can be terminated with no notice, at any time by the client company. If this happens you have to jump through hoops to prove that the termination was not your fault if you wish to remain "placeable" by MegaForce.
Job placement across a large spectrum of manufacturing jobs
Low pay, no real beneifits.
