Arman was hired to drive an airport shuttle for a rental car company back and forth from the airport to the rental car company’s off-site parking lot. When Arman was hired, he signed a written contract that stated specifically that he was an independent contractor. He was paid every two weeks, based on a rate per mile plus an hourly rate for waiting time. He drove the shuttle at times and to locations directed by the rental car company and was on call twenty-four hours a day. Is Arman an employee or an independent contractor?
