[Excerpt] The 200-page Human Rights Watch report is based on case studies across a range of industries, occupations and regions of the United States. The report recognizes that U.S. workers generally do not confront gross human rights violations where death squads assassinate union activists or collective bargaining is outlawed. But the absence of systematic government repression does not mean that workers have effective exercise of the right to freedom of association. The case studies in the Human Rights Watch report uncover a distressing pattern of threats, harassment, spying, firings and other reprisals against worker activists and a labor law system that is failing to deter such violations.
