DIM BULB: The U.S. Postal Service inspector general reported that the deficit-ridden agency could save as much as $335 million a year if it cleaned up its slipshod workers’ compensation practices. Some 16,200 USPS employees and retirees are currently on the long-term workers’ comp rolls — more than one-third of the total for the entire federal workforce. About two-thirds of the 150 case files reviewed by the inspector general “lacked claims forms, medical documentation or correspondence.”
