The International Longshore and Warehouse Union (ILWU) made good on its threat to stage a virtual strike on May Day, effectively shutting down all U.S. and Canadian West Coast ports. The one-day “work-stoppage,” said ILWU officials, is to protest the war in Iraq and comes at a time when the union is in the middle of contract talks with the Pacific Maritime Association (PMA).

For shippers, however, the event may signal that more trouble lies ahead. “Longshore workers are standing-down on the job and standing up for America,” said ILWU president Bob McEllrath. “We’re supporting the troops and telling politicians in Washington that it’s time to end the war in Iraq.”...read on

There's also a march planned.

On May Day 2008, longshore workers and other trade unionists will join together in a march starting at 10:30 AM at Mason St. & Beach St. and will rally at the Justin Herman Plaza. They will also join with the immigrant rights marchers. At 6:00 PM there will be a potluck at ILWU Local 34 which is located at 2nd St and Embarcadero next to the AT&T ball park.
