I get the appeal of a “garden leave” where you make your salary but don’t work. It’s a nice break after hard work before your next thing… but can you “quit” and voluntarily leave early? If you can quit the extended severance period, it would force employers to pay the market rate of their anti-competitiveness. If someone’s salary is X and they find a new job at 1.25X, then some would take X to do fully paid vacation for a few months after quitting, but surely some would force the old employer to pay up.
