Some former WorldCom employees in Iowa are up in the air about the loss of their jobs. The workers are still waiting for severance checks. About a hundred in Cedar Rapids and a handful in Iowa City lost jobs late in June when the corporation’s accounting troubles first surfaced, but with matters now in the hands of a bankruptcy court, they don’t know how long it will take to get the check that should accompany the pink slip. How much they get will depend on how long they’d been on the job and how much they earned. And WorldCom says it doesn’t plan any more layoffs, but that’s slim comfort to the former workers who have to wait and see if a judge will allow severance to be paid as the bankruptcy wends its way through the court.
