Feb 21 03:31 AM US/Eastern By JIM ABRAMS Associated Press WASHINGTON (AP) - New government workers will have to contribute about 3 percent of their salaries toward their retirement instead of the nearly 1 percent paid by those now on the federal payroll. That's one way Congress will pay for extending federal unemployment benefits as part of the deal to prevent Social Security taxes from going up next month. It's the latest example of how federal workers have become a target for both Republicans and President Barack Obama. In his proposed 2013 budget, Obama wants all federal workers to start picking up more of their pension costs, although he would give them a one-half of 1 percent pay raise next January. It has been more than two years since they got a raise and Republicans want to freeze their pay until 2014.
