On the "what does a business owe it's employees" argument, I tend to go with "nothing." Workplace loyalty vanished a long time ago. While some people feel they owe it to their company to give two weeks notice, a business won't necessarily do the same back. It's great if they do of course.
Two companies back, we got word that the head office in Dallas was going to shut the doors in July. Everyone got three months severance. They said that anyone that actually worked for that three months, would get the next three months, through December 31st, paid in full. I thought that was pretty cool. Of course, most people didn't do shit that next three months and were rarely in the office. I on the other hand, was shipped to numerous customer sites for that time, and might have been home a total of 10 of that 90 days.... Got my next job with one of those customers though, so that worked out.
