Companies with mobile workers are seeing increases in both the average cost per worker and the average mileage traveled by their workforces, according to mobile workforce management company Motus' annual Mobile Workforce Benchmark Report. Most companies pay employees a cost per mile, though they usually also employ other reimbursement methods for those workers who travel the most, according to the study. The survey, conducted between January and May, collected responses from more than 2,000 companies that have mobile workforces.
