Unions representing shipbuilders, nurses, longshoremen and other workers have intensified efforts to restrict artificial intelligence in workplaces, negotiating contract protections and organizing protests against specific tools.

At Bath Iron Works in Maine, the machinists union updated contract language last month to require early discussions with management on AI implementation. Union president Tim Suitter emphasized the need for worker input as the technology advances in defense manufacturing.

The International Association of Machinists and Aerospace Workers has developed model contract provisions and pushed companies for transparency on AI use. Similar moves appear in other sectors.

Nurses unions protested hospital contracts with Palantir in August, arguing the software could alter staffing and administrative roles. Longshoremen have demanded outright bans on automated equipment at ports.

AFL-CIO leaders have described AI as a major challenge for workers and called for guardrails including human oversight of employment decisions. UAW officials have labeled certain AI applications a threat to jobs in auto manufacturing.

These actions reflect union concerns over potential job displacement and surveillance. Public approval for unions remains high, with Gallup data showing strong support levels.

Critics note that resistance may overlook AI's capacity to boost productivity, reduce repetitive tasks, and create demand for new skills. Some unions have pursued partnerships for training while others prioritize limits or veto power.

Data centers powering AI have also sparked debate within labor, with construction unions securing work on projects while other groups push for moratoriums.

Negotiated agreements in entertainment, media and tech have produced rules requiring notification or consent before AI deployment in specific roles. Broader policy fights continue in Congress over federal standards versus state measures.

The pattern shows unions leveraging bargaining power where available, though most American workers lack such representation.
