The decision to increase wages had a high probability of effect on Walmart’s success, illustrated by Multiple Choice pilot tests confirming that turnover would decrease. lawsuits that had been dropped. support from labor and worker rights groups. increased morale among all employees. flexible schedules, more training, and more HR personnel.

pilot tests confirming that turnover would decrease.

Explanation:

Companies that have a lower turnover of employees are generally more successful than companies that don't because these companies spend less on job training for new staff, have a staff that is more motivated and the presence of regular staff that bond with customers will inspire those customers to buy more.

Walmart engaged in pilot tests to confirm this theory and increased wages in several test locations. These locations became more successful after the wage increase and so Walmart decided to apply it across the board.
