July 31 (Reuters) - Cash-strapped U.S. trucking company Yellow Corp (YELL.O) has ceased operations and is filing for bankruptcy after failing to reorganize and refinance over a billion dollars in debt, the Teamsters Union said on Sunday. Yellow, formerly called YRC Worldwide, did not respond to a Reuters request for comment. The company was the third-biggest U.S. trucker specializing in the less-than-truckload segment that combines shipments from different customers in the same trailer. The Wall Street Journal reported the closure of the trucking firm's operations citing notices sent to customers and employees. On Monday, another 128 union members at YRC Freight Canada, a unit of Yellow, were told not to report for work.
