Wal-Mart has a long history of failing to protect workers' rights and opposing their right to collectively bargain. Since 2009, Wal-Mart has been involved in more than 3,000 federal court lawsuits. Hundreds of these lawsuits are from workers claiming racial, sexual, religious or other bias in pay, promotions and other treatment.[8] Wal-Mart's participation in national business associations mirror these efforts to curtail workers rights and limit their ability to collectively bargain.
