In March 1970, between 150,000 and 200,000 postal workers staged the largest wildcat strike against the federal government in American history. It was illegal, no one was prosecuted, and soldiers sent to sort New York's mail could not do it. The settlement produced the Postal Reorganization Act and the independent Postal Service in 1971, with a lasting contradiction: public-service obligations funded like a business.

Strike participation estimates run from about 150,000 to over 200,000. Union accounts call 1970 a workers' victory, while others see the Kappel corporatization plan enacted with a labor settlement attached.
