That's really lousy management to shove all the responsibility on a 17 year company employee. The company should have known this could happen. There is no way they didn't think something like this could ever not happen. Management looks like idiots right now and they know it. It's sad they are looking for a fall guy to place blame. He made a mistake but there should have been measures in place to lessen the outcome for such a mistake. If he is terminated, he has a great wrongful termination case.
