As of December 31, 2020, we employed 9,342 drivers; 556 mechanics and maintenance associates for the trucking operation; 1,349 office associates for the trucking operation; and 1,045 associates for Werner Logistics, international, driving schools and other non-trucking operations. We also had 440 independent contractors who provide both a tractor and a driver or drivers. None of our U.S., Canadian or Chinese associates are represented by a collective bargaining unit, and we consider relations with our associates to be good.
