Andrea Smith has a daughter who turns eight on 20 December, five days before Christmas. Now the trucker’s birthday and Christmas plans have been thrown into disarray by the largest trucking firm bankruptcy in history.

“I’m not sure what’s going to happen or if I’ll get to be home if I’m able to find another job quickly. I’m crushed,” said Smith, a truck operator for Celadon, hours after the giant trucking firm declared it was going out of business.

Smith is one of about 4,000 truck drivers across the US who were notified on Monday that their employer was ceasing operations after filing for chapter 11 bankruptcy protection. The filing makes it the largest bankruptcy in trucking history.
