1981 – President Ronald Reagan fires 11,359 striking air-traffic controllers who ignored his order for them to return to work. In the 1980 presidential election, the Professional Air Traffic Control Organization (along with the Teamsters and the Air Line Pilots Association) refused to back President Jimmy Carter, instead endorsing Republican Party candidate Ronald Reagan. PATCO's refusal to endorse the Democratic Party stemmed in large part from poor labor relations with the FAA (the employer of PATCO members) under the Carter administration and Ronald Reagan's endorsement of the union and its struggle for better conditions during the 1980 election campaign. During his campaign, Reagan sent a letter to Robert E. Poli, the new president of PATCO, in which he declared support for the organization's demands and a disposition to work toward solutions. In it, he stated "I will take whatever steps are necessary to provide our air traffic controllers with the most modern equipment available, and to adjust staff levels and workdays so they are commensurate with achieving the maximum degree of public safety," and "I pledge to you that my administration will work very closely with you to bring about a spirit of cooperation between the President and the air traffic controllers." This letter gave Poli and the organization a sense of security that led to an overestimation of their position in the negotiations with the FAA, which contributed to their decision to strike. At 7 a.m. on August 3, 1981, the union declared a strike. Despite supporting PATCO's effort in his 1980 campaign, Ronald Reagan declared the PATCO strike a "peril to national safety" and ordered them back to work under the terms of the Taft–Hartley Act. Only 1,300 (10%) of the nearly 13,000 controllers returned to work. At 10:55 a.m., Reagan included the following in a statement: "Let me read the solemn oath taken by each of these employees, a sworn affidavit, when they accepted their jobs: 'I am not participating in any strike against the Government of the United States or any agency thereof, and I will not so participate while an employee of the Government of the United States or any agency thereof.'" He then demanded those remaining on strike return to work within 48 hours or officially forfeit their positions. On August 5, following the PATCO workers' refusal to return to work, the Reagan administration fired the 11,345 striking air traffic controllers who had ignored the order, and banned them from federal service for life. The FAA had initially claimed that staffing levels would be restored within two years; however, it took closer to 10 years before the overall staffing levels returned to normal. Reagan's firing of the government employees encouraged large private employers like Phelps Dodge (1983), Hormel (1985–86), and International Paper (1987) to hire striker replacements instead of negotiating in labor conflicts. In 1970 there were over 380 major strikes or lockouts in the U.S.; by 1980 the number had dropped to under 200, in 1999 it fell to 17, and in 2010 there were only 11.
