The contractor can provide proof of worker's compensation insurance coverage. The individual is not presently employed by the District to do the same type of work. Contractors are hired to provide a result and usually have the right to hire others to do the actual work. Usually contractors don't have a continuing relationship with a hiring company. The relationship can be frequent, but it must be at irregular intervals, on call, or whenever work is available.
Contractors control where they work.
If they work on the premises of the hiring company, it is not under that company's direction or supervision. Contractors determine the order and sequence that they will perform their work. Contractors are hired for the final result, and therefore should not be asked for progress or interim reports. Contractors are generally responsible for their incidental expenses. The contractor's investment in his trade must be real, essential, and adequate.
