Quicksilver Express Courier Inc. has agreed to pay $590,039 in unpaid minimum wage and overtime pay to 950 workers after a U.S. Department of Labor investigation determined that the company violated the Fair Labor Standards Act.

The company, based in St. Paul, Minn., has offices in Kansas City, Kan.; St. Paul; Phoenix; Lakewood, Colo.; and West Allis, Wis.

Brad Mitchell, a Labor Department spokesman, said Monday that drivers in the Kansas City area employed by the company between April 2006 and April 2008 are eligible for the payments, but he had no information about how many at the local office will receive them.

Quicksilver CEO Mike Crary couldn't immediately be reached for comment.

The agency's Wage and Hour Division determined that the company made deductions from drivers' pay for employer-required insurance and computer/GPS systems, resulting in minimum wage violations, the agency said in a release. Overtime pay violations occurred when bonuses were excluded from employees' regular pay rates and when drivers were improperly classified as exempt.

The Fair Labor Standards act requires employers to pay employees the federal minimum wage, currently $6.55 an hour, for all hours worked, and time and a half for hours worked in excess of 40 hours a week. The FLSA provides an exemption from both minimum wage and overtime pay for bona fide executive, administrative, professional and outside sales employees.
