In the summer of 1981, the union of federal air traffic controllers went on strike. They broke a federal law that does not allow government unions from striking. Reagan said that if the air traffic controllers "do not report for work within 48 hours, they have forfeited their jobs and will be terminated". They did not return and on August 5, Reagan fired 11,359 striking air traffic controllers who had ignored his order, and used supervisors and military controllers to handle the nation's commercial air traffic until new controllers could be hired and trained.
