Trucking sociologist Steve Isselli says employees giving up walking away is almost always the way it goes at these big trucking companies. Even with all the costs of recruiting, buying everyone a Greyhound ticket to the training, training all those new drivers, he says dealing with that much turnover is still cheaper than having all full-time employees or hiring veteran long haul truckers. Price is the only real way these companies can compete. And that keeps their profit margins super low.
