Biography
John C. Czarnecki was a Lawrence textile worker and strike-committee member arrested during the February 26, 1931 raid on the National Textile Workers Union headquarters. Police jailed the strike leaders as city officials sought to end the walkout. Czarnecki and Alex Danilevich remained in local custody after other organizers were transferred to federal immigration detention. The International Labor Defense sought to reduce their $20,000 bail and secure their release.
The February 27 Lawrence dispatch names this organizer among strike leaders beaten and jailed during the union-headquarters raid as Mayor Landers and the Citizens Committee sought a return-to-work vote. It reports total bail over $100,000 while mass picketing continued. This is contemporaneous strike repression, not a new custody episode separate from the existing February 26 arrest.
