(CNN) - Occupy protesters succeeded in shutting down overnight operations at California's port of Oakland on Monday night after a day of similar protests in several other U.S. cities.
The protests in Oakland have "disrupted workers trying to get to work and impaired the port's ability to operate," port spokesman Issac Kos-Read told CNN. Craig Merrilees, a spokesman for the International Longshore and Warehouse Union, said the port has told its members not to report for work for the overnight shift because of the mass of protesters at the port.
Earlier Monday, the port authority said in a statement there were "some delays of truck traffic" but said the port remained operational.
"Today's disruptions have been costly to port workers and their families in terms of lost wages and shifts," said Port of Oakland Executive Director Omar Benjamin, who suggested the movement should focus on "real solutions to the problems plaguing our economy."
On a normal night, several hundred people would be working the graveyard shift, Kos-Read said. Day shifts involve several thousand, he said. He said the protests have cost workers their wages, cost the city and region some revenue and could cause shipping firms to divert vessels to other ports.
"What has this accomplished?" he asked. "This is disrupting the 99%"
Oakland Mayor Jean Quan concurred, saying the Occupy movement isn't thinking of the consequences of its actions and who it is actually hurting.
"They are saying ... they have to get the attention of the ruling class. I think the ruling class is probably laughing and people in this city will be crying this Christmas," Quan said. "It's really got to stop."FULL STORY
