Walmart will begin subsidizing the cost of college for store workers who work toward company-selected degrees at schools that have teamed with the retailing giant.

In exchange for a contribution of $1 a day, the company said it would cover the price of tuition and books for an estimated 68,000 associates over the next five years from all Walmart and Sam’s Club stores in the U.S. The Bentonville, Ark.-based retailer said its goal is eliminating the need for workers to obtain student loans, addressing “one of the biggest hurdles that keep people from returning to college.”
