with the state-sanctioned All-China Federation of Trade Unions (ACFTU) on representation for its 28,000 staff. However, the All-China Federation of Trade Unions has been criticized because it is the only trade union in China and as a tool of the government, ACFTU has been seen as not acting in the best interest of its members (workers), bowing to government pressure on industry growth and not defending workers' rights. In November 2012, the United Food & Commercial Workers joined with several Walmart workers with a plan to go on strike on Black Friday at several stores nationwide in protest to low pay, an increase in health insurance premiums, and not being given the option to have the day off or having Thanksgiving off. Walmart has countered this by saying that the strike is illegal due to the union not being sanctioned by the company, and that the striking workers are a small minority of the company's workforce, with the vast majority of workers willing and ready to work the retail industry's busiest day of the year. In May 2013, Walmart employees associated with a union-backed labor group called OUR Walmart began what it says will be the first "prolonged strikes" in Walmart's history. For Thanksgiving 2013, CNN estimates that approximately a million United States Walmart employees would work over the course of the holiday, with big specials starting at 6:00 pm on Thanksgiving Day. The company stated that employees would receive "a nice Thanksgiving dinner at work", extra "holiday pay", and 25% discount off one purchase, regardless of how many items are purchased at that time. According to the Cleveland Plain Dealer, the extra holiday pay equaled the average daily shift the employee worked during the previous two weeks. Walmart would also expand its one-hour guarantee from three items the year before to twenty-one items. This means that a customer standing in line for such an item from 6–7 pm or from 8–9 pm would be guaranteed to get it at that price some point before Christmas. In July 2019, the Walmart subreddit was flooded with pro-union memes in a protest to the firing of an employee who posted confidential material to the subreddit. Many of these posts were angry with Walmart surveying its staff on the Internet. The posting of the union content is in a response to the aforementioned alleged anti-union position Walmart has taken in the past. Surveillance
