No. They will ofer a "garden leave". This means, you get paid and stay employed as much as the grace period is over. I think the only restriction is not entering the company's premises.
For executives, is not uncommon that they stay one year in the "garden leave", having all the perks too.
When I left Autonomy, I had such a "garden leave" for 3 months. I stayed at home and received normal salary. Was nice, but boring.
We have lessons to learn from European paradigms as you point out. However I think you are a little harsh on founders, the pursuit of fame may be an issue for a small minority but is hardly a universal issue.
