As Gov. Chris Christie (R) crisscrosses New Jersey to push an overhaul of the state’s troubled public pension system, the governor’s road map to pension reform is running into roadblocks, the Wall Street Journal reported today. Sixteen unions representing public sector workers are ramping up their fight to force the administration to invest more into the pension system. They say that they plan to file two lawsuits calling for Christie to make a larger pension payment in his newly introduced budget. The unions won a court decision last month after Christie didn’t make the fully promised payments over the past two years. “It’s a legal obligation,” said Hetty Rosenstein, New Jersey director of the Communications Workers of America. Even the union that agreed to discuss some of the changes, the New Jersey Education Association, says Christie exaggerated its degree of cooperation. Christie is undeterred, taking his pension push directly to residents in a series of town hall meetings, including one in this Bergen County borough on Wednesday.
