A union in California goes up against the rising tide of automation.
East Coast ports can learn a lot from Los Angeles about handling giant ships.
A deal has been reached to end an eight day strike at the ports of Los Angeles and Long Beach, which handle almost half of all the cargo that arrives by sea in this country.
Already the strike has idled thousands of trucks and trains that take containers from the Ports of Los Angeles and Long Beach to factories and distribution centers.
It's possible America's busiest ports may not stay busy. Southern California currently receives most of the imports shipped from Asia. But that could change with a major expansion of the Panama Canal.
