Wal-Mart recently terminated an arrangement it had with a non-profit group to hire mentally disabled workers, citing a corporate policy against using outside employment agencies. The arrangement, typically called an “enclave” arrangement, provided Wal-Mart with workers and a job coach to help the mentally disabled perform their jobs effectively. While Wal-Mart claims it has offered interviews for direct employment to the workers whose jobs were terminated, the company is facing growing criticism of its treatment of disabled workers.
