Did anybody who worked in the Oakland port or the closed down banks lose any paid work hours due to protests?

yes many people did

Many were reported to have taken a mental health day, or vacation day or probably called in "sick".

Oakland called for a day of "no work no school".

NOTE:Amazingly there were several banks who backed the protest. Many were also using the day to join in the protest, It is difficult to sort out feelings about those who work at the corrupt banks. Everyone needs their pay check, but if you knowingly work for companies that are known for their corruption and lack of concern for their customers or those they lured into 'false pretense' home loans...well, then you pay the piper.

NOTE:The specter of workers on strike and a day of mass protest was enough to prompt many of Oakland's largest corporate entities to shut down for the day, adding even more to the numbers in the streets.

Truckers lost money, but many accepted that fact, realizing the protest included them. The following day the port was busy with truckers making up the runs that were halted the day before. (I'd be more concerned with those who had to stop working due to differing types of radiation detected coming from other countries.)
NOTE:"This event is long overdue," said James Curtis, an executive board member of the International Longshore and Warehouse Union (ILWU) Local 10. "Now they have awoken a sleeping tiger.

The port arbitrator made a ruling that signaled the Oakland docks would be shut down for the night.

NOTE: The demonstration shut down the evening shift when longshore workers refused to cross the picket line of some 15,000 people.

Members of UNITE HERE, the Coalition of Black Trade Unionists, United Food and Commercial Workers Local 5, SEIU Local 1021 and others joined the protest at the docks.

NOTE: The Alameda County Labor Council called on its membership and staff to support the day of action November 2--and in the evening, it organized a barbeque at Oscar Grant Plaza to feed thousands of people who streamed into the city center after work hours.

NOTE:Meanwhile, Teamsters Local 70 parked its boldly painted 18-wheeler in the middle of the plaza.

Among the participants during the day of action was a sizeable delegation of Iraq and Afghanistan war veterans who came to show their solidarity with Scott Olsen

NOTE:Hundreds of city workers from Service Employees Union (SEIU) Local 1021 participated in the protest. City workers and teachers used the day to join the protest.

NOTE: Longshore men refused to take work on Nov 2 to show solidarity. "Oakland is the economic engine for the whole Bay Area," Jack Heyman, a retired dockworker and activist in ILWU Local 10, told a Fresno public radio station. "Thousands are marching on the port, which is controlled by the 1 percent, the big capitalists, and by marching on the port and shutting it down, it shows not just Oakland but the whole world the power that the working class has."

Heyman thanked the young longshore workers who didn't show up for work in the morning of November 2, crimping the port's operations from early in the day. "I commend the young people who refused to take jobs this morning," said Heyman. "That's why ship owners had a real difficult time getting together longshore crews.

So yes, some lost a few hours of work and some a day's wages. But is a huge movement to try and turn around the corruption that has ruled the U.S. to be halted due to a day's loss of wages? Every revolution has it's price, and it is certainly worth it and as stated in the above (yes, wall of text) and many were willing to lose the pay they would have made.

The protest impacted large corporations and who can cry for them???

To make loss of pay an issue to try and negate the whole movement is ludicrious. It was one day and with the show of solidarity of all types of workers and their concern over the state of the country, the moment has made it's statement and will continue to do so, as citizens carry their renewed sense of power with them into the workplace and the corrupt are now in the spotlight and had best watch their future actions.
