The document discusses the 1981 air traffic controllers strike organized by the Professional Air Traffic Controllers Organization (PATCO) union. Over 13,000 of PATCO's 17,500 members went on strike to demand better pay and working conditions. In response, President Ronald Reagan threatened to fire any controllers who did not return to work within 48 hours. When the strike continued, Reagan fired over 11,000 striking air traffic controllers and banned them from future federal employment. The strike weakened unions and demonstrated Reagan's opposition to organized labor.
