In Ace Doran Hauling Rigging Co. v. NLRB, supra, 462 F.2d at 194 (enforcing Board determination of employee status where drivers drove exclusively for company, and performed duties similar to those of other employees, even though driver-owners could refuse trips and were permitted to backhaul), the "exclusivity" principle was utilized to distinguish between those drivers who were employees because they "dr[o]ve `exclusively' for Ace," and those who also performed other, unrelated work for the truckowner and were therefore nonemployees.
