The main purpose of this legislation is to ensure that certain employees, specifically truck drivers, receive overtime pay. It aims to amend the Fair Labor Standards Act of 1938, which currently allows some employees to be exempt from receiving overtime wages. The goal is to provide fair compensation for workers who put in more than the standard number of hours. The key provision of this legislation is the removal of the exemption that allows certain employees, particularly those in the trucking industry, to work over 40 hours a week without receiving additional pay.
