(Part of the Railroad Workers United convention, but open to all.) By understanding production systems and supply chains, and drawing on our own experience, logistics workers can identify chokepoints and vulnerabilities that give us leverage to win. Historically workers have used this power to win better wages, benefits, and working conditions, and even to block arms from being shipped to war zones, such as to Central America in the 1980s or Gaza last fall. Lessons from those actions apply to the war on Iran today.
