A contractor is hired for a specific job or skill, but not as a regular employee. Contractors are often used for specific building, renovating or repair skills.
While some contractors are excellent, others are not as good. An excellent contractor knows how to do the job safely. He or she will be able to guide you through the choices -- such as which materials or design may work better for you and why. A less competent or ethical contractor may rip out all your kitchen appliances for a kitchen remodel and then not come back to complete the job until weeks later.
