The U.S. Supreme Court agreed to hear a case that could determine whether companies such as Amazon.com Inc. must pay workers for the time they spend waiting to clear security checks at the end of their work shifts.

The case revolves around workers at Amazon warehouses in Nevada, who had to pass through security checks as part of an anti-theft procedure.

The workers, former temporary employees at Amazon contractor Integrity Staffing Solutions, said they spent nearly 30 minutes some days waiting for the checks. In a 2010 lawsuit, they argued they must be compensated for that time under the federal Fair Labor Standards Act (FLSA), said Reuters.

The U.S. Court of Appeals for the 9th Circuit ruled last April that the workers' suit could go forward, prompting several similar lawsuits against Amazon, the world's largest online retailer, and its third-party warehouse contractors, in federal courts around the country, said Reuters.

Integrity, which is represented in the high court by former U.S. solicitor general Paul Clement, argued that the 9th Circuit's ruling conflicted with other court decisions that said workers do not need to be paid for similar post-work duties that are not a part of their regular work tasks, said Reuters.

"Security screenings are indistinguishable from many other tasks that have been found non-compensable under the FLSA, such as waiting to punch in and out on the time clock, walking from the parking lot to the work place, waiting to pick up a paycheck, or waiting to pick up protective gear before donning it for a work shift," Integrity wrote in a brief to the court.

The case is Integrity Staffing Solutions, Inc v. Jesse Busk and Laurie Castro, U.S. Supreme Court, No. 13-433.
