I never heard of an executive being pushed to earn less money the way executives are pushed to resign.
Usually is quite the opposite, companies pay resigning executives a wealth sum as it is in the best interest of the company that the burned executive leave as soon as possible and with no intentions to harm the company after leaving. The board usually couldnt care less about the money a leaving executive gets.
An executive leaving money on the table (and distributing among other employees) is extremely rare and I think your cynism have no logical thinking support here.
