Walmart (WMT  ) is set to undergo a massive organizational overhaul that will see many workers receiving increased pay in exchange for increased responsibilities. Workers affected by the organizational changes will receive wages of $15 and up.

The organizational changes by Walmart will see some 165,000 employees being reorganized into small cross-trained teams assigned to certain areas of the store. Within their designated areas, employees are responsible for keeping items in stock and ensuring that displays meet Walmart's standards.

One of the most notable aspects of the changes is the increased pay, which will see many employees receiving a minimum wage of $15, a change that has been pushed for by many labor advocacy groups across the country. Specialized roles such as team lead roles will start at $18 an hour but can go as high as $30. Some salaried jobs will also see a wage increase.

"Through this new, tiered structure for team leads, we're creating room for pay and career growth while investing in areas like pickup and delivery as customers increasingly turn to those options," said Walmart COO Dacona Smith. "We are re-investing in several ways to provide associates with higher and more consistent base pay. Likewise, for these select hourly roles, this increase will also take the place of the regular quarterly bonus and become part of their base pay going forward, offering more predictability and more pay in their hourly wages."

The wage increase matches raises issued by Walmart's competitors, helping the retailer stay competitive in the labor market. Target (TGT  ) raised its starting wage to $15 an hour in July, while Amazon (AMZN  ) had raised its starting pay to $15 an hour for its distribution center workers.

The new organizational structure had been piloted previously at Sam's Club and Walmart Neighborhood Center locations. According to Walmart, the groups were more supportive, with employees being closer-knit when placed into smaller teams that had them working with the same people regularly.
