NLRB's non-communist affidavit for unions: 1955 ca.
A copy of a National Labor Relations Board (NLRB) non-communist affidavit circa 1955 that was required of union officials if they were to utilize the the NLRB.
Compliance with the affidavit requirement of the 1947 Taft-Hartley Act was initially debated within the labor movement.
At first the CIO urged non-compliance as a means of rendering the anti-labor act moot, but as anti-communism came to the fore during the second Red Scare, centrist and right wing union leadership complied.
Locally, the D.C. cafeteria union staged a strike in 1948 that was in part a result of its refusal to cooperate in signing the affidavits.
Left leaning and communist led unions that refused to comply were ultimately expelled from the CIO. Some managed to survive the initial raids by AFL and CIO unions, but ultimately merged with their rivals decades later. Some of these unions fell apart during this period.
The west coast Longshore and Warehouse union is a survivor from the non-compliance days along with the United Mine Workers.
The requirement was struck down by the U.S. Supreme Court in 1965 in the case of the United States vs. Brown.
