With over 2.3 million employees worldwide, Walmart has faced a torrent of lawsuits and issues with regards to its workforce. These issues involve low wages, poor working conditions, inadequate health care, and issues involving the company's strong anti-union policies. In November 2013, the National Labor Relations Board (NLRB) announced that it had found that in 13 U.S. states, Wal-Mart had pressured employees not to engage in strikes on Black Friday, and had illegally disciplined workers who had engaged in strikes.[143] Critics point to Walmart's high turnover rate as evidence of an unhappy workforce, although other factors may be involved.
