During layoffs session last year, the company I work for immediately removed people from the corporate directory, and then went to the guy who had made the unofficial facebook and made him hide them in his tool too. They still technically worked there during the WARN period, so they didn't have epitaphs either. That went over about at well as you'd expect.

This time around, the laid off people show up as on vacation. If you see a team of people all on PTO until the end of May, you can presume that team is donezo.
