Employees of a county public works department used county-owned vehicles to travel to job sites where they inspected the work of subcontractors. The vehicles contained the tools and equipment the employees used on the job and served as their offices at the job sites. The employees were not allowed to drive the vehicles to their homes at the end of the day. Instead, they were required to bring them back to secure, county-owned parking areas, where they also retrieved their own private vehicles. The employees were not paid for the time spent traveling from the remote parking areas to their first job site of the day. Nor were they compensated for the time spent bringing the vehicles back to the parking areas from their last job site of the day. Is this travel time compensable under the FLSA?
