Yeah. But again, it basically means you have no handover of anything, and in many (most?) places around the world you are still required to pay employees for a long period after notice. So you have an opportunity for handover that you are paying for, but that you aren't using.

The risk to the business from just dropping things without proper handover shouldn't be ignored in comparison to the risk of an employer going crazy after being notified their last day is 90 days ahead.

"Graveyards are full of essential people" (Bill Clinton). If there is someone who has information such that a handover is needed you as management screwed up by not preventing it in the first place. The person might have died and then there is never a handover possible.

Paying severance is very common even in the US where it isn't required by law (though generally not as long as Europe requires). Severance is what you pay people AFTER their last day.
