A small percentage of Wall Street workers who have jumped ship from a 'marquee' firm to a smaller firm have gotten 'guaranteed employment contracts' in which the company guarantees to pay them X amount a month for 1-2 years. Basically, they don't get laid off because the company has to pay them anyway.
Wall Street employees can get 60% to 80% of their take home pay from bonuses. So while I'm sure they would be a lot of money over those months, it wouldn't be anywhere close to the actual pay once you include bonuses.
