COLUMBUS - State and federal officials offered assistance last spring to DHL and its affiliate companies to try to keep workers in Ohio and help with expansion or merger efforts with other companies.

But most of the efforts were rebuffed, prompting investigations of the German company's decision to shut down domestic operations and lay off up to 1,000 workers in Wilmington.

DHL's announcement will have a domino effect that threatens thousands of more jobs with contractors - specifically ABX Air, which runs its Wilmington hub and employs another 7,000 workers, including 5,000 in Ohio. Another contractor airline, ASTAR, employs another 1,000 in Wilmington.
