During the first weeks of 2019, tens of thousands of striking workers brought to a halt virtually all the maquiladora manufacturing plants in the industrial Mexican city of Matamoros, just across the US border with Brownsville, Texas.
In a remarkable display of class unity and power, workers defied threats of retribution and violence from companies, union thugs, police and the military, and shut down a significant section of the closely-interconnected supply chain in North America.
Key to organizing their struggles across different companies and sectors was the formation of rank-and-file strike committees. Daily reports by the World Socialist Web Site played an important role in guiding the struggle and winning broader support.
