Security staff at major tech firms including Google OpenAI and Anthropic in California have issued a 72-hour strike notice starting September 18. Represented by SEIU-USWW the workers demand better pay healthcare and training after months of stalled contract negotiations with security firms. The strike could force office closures or remote work for employees at companies like Amazon Microsoft and Meta. While talks continue the union plans a march to Salesforce Tower highlighting ongoing disputes over compensation and working conditions for approximately 14000 security personnel in the region.
