In the 210-page report, “Discounting Rights: Wal-Mart’s Violation of US Workers’ Right to Freedom of Association,” Human Rights Watch found that while many American companies use weak US laws to stop workers from organizing, the retail giant stands out for the sheer magnitude and aggressiveness of its anti-union apparatus. Many of its anti-union tactics are lawful in the United States, though they combine to undermine workers’ rights. Others run afoul of soft US laws.
