An employee welcomes customers at a Wal-Mart Stores Inc. location in Burbank, California, U.S., on Thursday, Nov. 16, 2017.

Walmart is testing out a new employee structure within its stores in an attempt to cut down the size of its store management staff.

The nation's biggest employer is looking to see if it can have fewer midlevel store managers overseeing workers, with these managers seeing both their responsibilities and their pay increase.

Walmart has been trying to trim its labor costs, but still needs to retain workers and attract talent in a tight labor market.

The new structure is already in place at 75 of its stores, and will be expanding to departments across 50 other supercenter locations over the next month.
