New York ( CNN ) -- A group of union-backed organizations joined the loosely defined Occupy Wall Street movement again Tuesday , leaving behind the confines of New York 's financial district for the posh neighborhoods that dot Manhattan 's Upper East Side , according to multiple group representatives . Crowds also swelled in Lower Manhattan 's Zuccotti Park , where demonstrators waved placards and chanted slogans attacking corporate greed and social inequality . The union-organized march , meanwhile , took protesters past the homes of well-to-do residents like billionaire David Koch , News Corp. CEO Rupert Murdoch and JP Morgan Chase CEO Jamie Dimon . Organizations such as UnitedNY , the Strong Economy for All Coalition , the Working Families Party , and New York Communities for Change were accompanied by protesters typically based in Zuccotti Park , a privately owned park in New York 's financial district . The Upper East Side march was `` in support '' of the Occupy Wall Street movement , but was not organized by it , said T.J. Helmstetter , a spokesman for Working Families Party , a coalition of New York community and labor groups . Protesters hopped on the subway , emerging at Fifth Avenue and 59th Street near Central Park , where organizers held a press conference that addressed both New York-centric themes , such as state taxes , and the movement 's broader concerns of social inequity . `` We are the 99 % , '' the group chanted , a reference to their insistence that most Americans lack the influence in their country 's political and financial affairs enjoyed by the elite 1 % . `` I think it 's time that these people realize that people are hurting in this country and it 's time to reform what 's going on in Washington , '' said New York resident Lenore Silverstein , who attended Tuesday 's march . Emily Monroe , a North Carolina college student and marcher , said the city 's wealthiest `` are buying billion-dollar apartments and living lavishly , while we are just trying to sustain ourselves . '' `` The American dream is no longer possible because these people are stealing from the middle class , '' she told CNN Radio . New York Mayor Michael Bloomberg , meanwhile , said authorities will defend protesters ' right to demonstrate , but he does n't appreciate `` the bashing of all of the hardworking people who live and work here . '' `` Our city depends on the jobs that the financial services industry provides , '' Bloomberg said during a news conference in the Bronx . He added that he did n't understand what the picketing of wealthy and prominent New Yorkers is intended to achieve . The mayor 's comments coincided with a state comptroller report released Tuesday that predicts Wall Street could lose an additional 10,000 jobs by the end of next year , raising the total number of jobs lost in the securities industry since 2008 to 32,000 . Earlier , in Boston , 129 protesters were arrested during a similar demonstration Tuesday , mostly for `` unlawful assembly and trespassing , '' said police spokesman Eddy Chrispin . The group allegedly blocked traffic and refused to disperse while marching to `` areas of the city where they had n't been previously , '' he said . Protesters have been occupying Dewey Square Park in downtown Boston , but expanded to the neighboring Rose Fitzgerald Kennedy Greenway on Monday night . Protesters were given a 1:30 a.m. deadline to move back to Dewey Square . Those who did not were arrested . The nationwide Occupy movement has been largely peaceful , though it has led to some skirmishes with police and arrests . It has also stoked fervent public debate , including among politicians . Democrats have generally offered sympathy for protesters ' concerns while several Republicans , among them 2012 presidential candidates Herman Cain and Newt Gingrich , have described the demonstrations as `` class warfare . '' The movement shows few signs of slowing down . Rallies and marches have been held in numerous towns and cities in recent days , with many more planned . That includes a `` Call to Action Against Banks '' planned for Saturday , which New York 's Occupy Wall Street announced on its Facebook site . `` No longer will banks take our homes . No longer will banks rob students of our future . No longer will banks destroy the environment . No longer will banks fund the misery of war . No longer will banks cause massive unemployment . And no longer will banks create and profit from economic crisis without a struggle , '' according to the online message Monday . It then urges people to `` visit your local Bank of America , Wells Fargo or Chase ( branches ) and let them know , we will not allow business as usual . '' `` We . Will . Occupy . Everywhere , '' the posting ends . CNN Radio 's Steve Kastenbaum , CNNMoney 's Charles Riley and CNN 's Marina Landis contributed to this report .
