Despite a walk-out by members of IATSE 683 film laboratory technicians in solidarity with CSU, open fighting between CSU members and studio security forces and a vote by the Screen Actors Guild to effectively turn their back on CSU hampered the CSU's efforts. This was a strike that the CSU would never recover from, lasting some 13 months before it voted to permit long-unemployed, impoverished members and supporters to cross the picket line and return to work. The CIO also came to the aid of the struggling CSU members and assisted them in finding jobs in other CIO industries.
