I have, on numerous occasions, come in to work to find that a colleague was laid off without anybody giving advance notice to them or anyone on the team. Just, poof they're gone, hey team let's pick up Jimmy's tickets now! If that person's manager was not my manager, I was not even told after they were laid off -- I found out when emails went unanswered and I had to go looking for them. I think that's pretty typical, unfortunately. Anybody who would judge a coworker for leaving without notice shows a pathological lack of empathy. Doing so publicly would be a great way to damage your own reputation.
