If one receives a 1099-MISC with income reported in Box 7 (Nonemployee compensation), this indicates that the recipient is self-employed. That doesn't necessarily mean that the recipient owns his own business...only that he is being paid as an independent contractor.
Sometimes employers pay in this fashion to avoid paying their portion (1/2) of the employee's Medicare and Social Security taxes. T"he IRS does have "rules" for defining who is an employee or not. If the recipient of the 1099 is required to be at a certain place at specific times, this typically indicates that they should be classified as an "employee". This may be something that "he" would want to discuss with the employer.
