The PATCO Strike of 1981 was a union-organized labor strike of air traffic controllers (ATCs). Following a decade of successful strikes in other industries, the Professional Air Traffic Controllers Organization (PATCO) declared a strike on August 3, 1981, demanding higher wages and more benefits. Despite 13,000 ATCs striking, the strike ultimately failed, as the Reagan administration was quickly able to replace the striking ATCs. As a result, PATCO was decertified, and the decline in labor unions in the United States increased.
