An Alaskan native corporation, Chugach Management Services, which handles infrastructure maintenance at Tampa's MacDill Air Force Base, reports it is eliminating 149 jobs at the base on Oct. 31. The business, a unit of Chugach Alaska Corp. in Anchorage, has a 10-year contract with MacDill that expires Oct. 31. Chugach president Barney Uhart in Anchorage said that his company bid on a new, though smaller, MacDill contract and is waiting to hear whether it has been accepted. Until then, the company's 149 jobs at MacDill were reported as ending on Florida's Worker Adjustment and Retraining Notification list of larger-scale layoffs. Uhart says about 210 employees work for Chugach Management and a subcontractor in Tampa. The Alaska parent has annual revenues of about $900-million.
