The company, not surprisingly, is also known for brutal tactics against workers. It is known for retaliating against employers who attempt to organize. Walmart employees often rely on food stamps and Medicaid, because of insufficient wages and lack of adequate health care. In 2005, according to St Louis Federal Reserve President William Poole, Walmart "observed among their own employees a reduction in health care utilization – that is, fewer doctors' visits – but an increase in emergency room visits. Apparently employees are struggling some to make the co-payments and that kind of thing, again emphasizing the stress that exists in many lower-income households." It is also a huge political force - the company successfully fought off a massive gender discrimination suit struck down by the Supreme Court on technical grounds. New York Public Advocate Bill de Blasio unveiled the site Six Degrees of Walmart after the company was caught in a bribery scandal in Mexico (where it is the largest private employer).
