Store managers for Harbor Freight have filed a class action lawsuit seeking unpaid overtime compensation. They claim that they were misclassified as exempt from overtime because they typically performed manual labor and worked 60 - 90 hours a week. The suit was filed under the Fair Labor Standards Act in federal district court in Kansas City and involves persons employed by Harbor Freight in Kansas, Nebraska and Missouri.
