Friday, April 6- On Tuesday night, April 3rd, union shipyard workers in Pascagoula, Mississippi voted by a roughly 60-40 margin to accept a new offer from Northrop Grumman and return to work. The vote ended a twenty-eight day strike of 7,000 workers from 13 unions at the Ingalls shipyards, the longest strike in decades. The new contract contains increased health insurance costs, but also a cost of living increase and other very modest financial improvements for workers, which some say are far offset by the increased cost of living on the Mississippi coast post-Katrina.
