I have always found the way layoffs being done in the US very strange and unnecessarily dramatic for both parties. If you are leaving, you should be leaving in a professional manner. Do your best at work until the last day of your employment.

Same if you are letting someone go, treat them with dignity and respect until their last days at the company. Telling someone to pack their bags the same day they are getting the notice sounds very cruel.

I don't see how this "burn all bridges" strategy can benefit anyone.
