Last week, Anthropic received a notice from Allied Universal, its security staffing contractor, indicating that its employees might go on strike. According to a person familiar with the matter, the AI company responded by telling its own workers to avoid coming into San Francisco offices on Monday and Tuesday as a precautionary measure. The company maintains offices in the city where it develops its Claude AI assistant and conducts research operations.

Allied Universal did not respond to requests for comment from Business Insider regarding the strike notice or its communications with Anthropic. The security services firm provides staffing for numerous corporate clients across California and nationwide. Meanwhile, Anthropic declined to comment on the stay-at-home mandate issued to its employees.

Union Negotiations Continue Without Strike Authorization

The Service Employees International Union (SEIU), which represents workers at Allied Universal, told Business Insider it is currently engaged in protracted contract negotiations with Allied and other California security firms. The union emphasized that it had not called a strike authorization vote or issued any strike threats for this week, contradicting the premise of Anthropic’s work-from-home directive.

SEIU covers thousands of security workers across California and has been negotiating for a new contract since April. The union campaigns for higher wages, better healthcare coverage, and more comprehensive job training for the security professionals it represents throughout the state. These negotiations reflect broader labor concerns in California’s service industries, where workers increasingly demand improved compensation and benefits.

The disconnect between the strike warning Anthropic received and the union’s actual position raises questions about communication channels between security contractors and their clients. It remains unclear whether Allied Universal issued the warning based on internal assessments or miscommunication about the status of union negotiations. The incident demonstrates how labor tensions can ripple through the corporate ecosystem even when strikes do not materialize.

Security Concerns Escalate Across Tech Industry

Security spending has ramped up significantly in the wider tech industry over the past few years. The Wall Street Journal reported that Anthropic and OpenAI have dealt with several threats against their employees, prompting increased investment in physical security measures and protective services. The AI sector faces particular scrutiny due to concerns about the technology’s potential impact and the controversial nature of some AI development decisions.

These security concerns extend beyond physical threats to encompass a broader range of risks facing tech companies. The AI industry in particular has become a focal point for activism, regulatory attention, and public debate about the future of the technology. Companies developing frontier AI systems maintain heightened security protocols to protect their employees, intellectual property, and research operations from various potential threats.

The precautionary work-from-home directive issued by Anthropic reflects this security-conscious environment. Even the possibility of a strike by security workers prompted immediate action to ensure employee safety and maintain business continuity. This approach demonstrates how AI companies prioritize risk mitigation even when threats remain hypothetical or unconfirmed.

Hybrid Work Policy Remains in Effect

Anthropic maintains a hybrid in-office policy that generally requires staff to be in the office at least 25% of the time, according to job postings reviewed by Business Insider. This policy balances the company’s need for in-person collaboration with flexibility for remote work, a common approach among tech companies in the post-pandemic era. The temporary work-from-home directive represents a deviation from this standard policy driven by specific security concerns.

The company’s willingness to adjust its office attendance requirements demonstrates flexibility in responding to potential disruptions. By erring on the side of caution, Anthropic avoided any possible complications that might have arisen if a strike had actually occurred. This decision-making approach reflects the broader tech industry’s emphasis on employee safety and operational continuity.

Company Prepares for Major Public Market Debut

Anthropic prepares to file for its initial public offering as soon as August, having filed its confidential S-1 draft in June. On secondary markets, investors have propelled the company to a $1.5 trillion valuation, reflecting enormous confidence in the AI startup’s prospects and competitive position. The company competes directly with OpenAI in developing large language models and AI assistants for consumer and enterprise applications.

The anticipated IPO represents one of the most significant public market debuts in the technology sector. Anthropic’s valuation places it among the most valuable startups in history, driven by investor enthusiasm for artificial intelligence and the company’s technological achievements. Founded by former OpenAI executives, Anthropic positions itself as developing AI systems with enhanced safety and reliability characteristics compared to competitors.

The security incident and work-from-home directive arrive at a sensitive time as the company prepares for intense public market scrutiny. Investors evaluating the IPO will examine operational risks, including labor relations affecting service providers like Allied Universal. While the strike threat did not materialize, the episode illustrates potential vulnerabilities in the company’s reliance on third-party security services during a period of labor activism in California.
