Question: The taxi drivers at 4-Star Cabs pay the company a daily rental fee for the use of the company cabs, but get to keep all the fares that they earn during their driving shifts. The drivers determine their working hours, and must pay for the gas they use during their shifts. The company carries an "umbrella" auto insurance policy that covers the drivers, but it does not provide any benefits to the drivers. Are the drivers "employees" under the NLRA? Explain.
