The workers will be able to make those requests up to eight times a year, Walmart said. The Even app also has financial planning tools to help employees manage their expenses.
Walmart and its partners, Silicon Valley-based startups PayActiv and Even, said the new perk is meant to help employees who have unexpected expenses between paychecks.
Walmart has long faced criticism for underpaying its employees. But the company has been working to improve conditions for its workforce by investing $2.7 billion over the last couple years in higher wages, training, and better scheduling management.
"Traditional approaches to workforce well-being often focus solely on physical health, but we know from listening to our associates that financial well-being is just as important," Walmart chief people office Jacqui Canney said in a statement. "We're investing to give our people financial tools that help provide more stability in their lives, which we believe will empower them to be all they can be when they are at work serving our customers."
