Legal Question in Workers Comp in California

If you plan to tell him exactly what to do, what hours to work, can fire him, make deductions from his paycheck--he is not an independent contractor. Unless he has some very technical knowledge, no one will believe he is a contractor.

I suspect you do not for that short of a period of work.
