£10k to leave?
This would show a significant book saving over the next year as long as it was not tied to the revenue generated by the staff member (and how do you measure that in a large organisation?).
So given the appropriate metrics you could achieve big bonuses every year by cutting staffing costs, then cutting infrastructure costs as you "consolidate" offices. At some point you will be last person standing, but with plenty of money in the bank and pension fund and a solid record as a high achiever.
Just another version of an asset stripper.
Expect the smouldering remains to be sold for $1 in about 10 years time.
