I would say that happens more in the Public Sector actually. Mandelson resigned twice as MP but got back in to Cabinet twice and then the EU Commission.
On the Tory side, Chris Paton has had a few lucrative, dream jobs since his electorate kicked him out in 1992.
I can also point to some NHS Executives, Directors of service etc that play musical chairs, despite questions over their achievements, or lack of.
I have seen it in the private sector as well, but if I as a business owner, go and hire someone who has just closed a business, or been a key part of it, I am answerable for that decision.
