No training Contractors typically do not receive training by the hiring firm. They use their own methods to accomplish the work. Services don't have to be rendered personally Contractors are hired to provide a result and usually have the right to hire others to do the actual work. Work not essential to the hiring firm A company's success or continuation should not depend on the service of outside contractors. An example violating this would be a law firm which called their lawyers independent contractors.
Contractors set their own work hours.
Not a continuing relationship Usually contractors don't have a continuing relationship with a hiring company. The relation ship can be frequent, but it must be at irregular intervals, on call, or whenever work is available. Contractors shouldn't hire, supervise, or pay assistants at the direction of the hiring company. If assistants are hired, it should be at the contractor's sole discretion. Time to pursue other work Contractors should have enough time available to pursue other gainful work.
