As we mark the 52nd anniversary of the March 1970 postal strike people may be interested in this article I (Jeffrey B. Perry) wrote on the eve of the July 1978 postal wildcat strikes entitled "What's Behind Postal Strife" (in "New York Workers' Perspective, an Independent Newspaper of Labor and Community," July 1978). An image of the article is posted on my Facebook page of 3/19/22.
