Everyone who's paid by the hour or any other period of time, whether they be a surgeon or a street cleaner, is indirectly financially involved in doing a good job in the long run, because someone is watching how they do and that can affect their future earnings. A surgeon wants to achieve the best possible outcomes for patients partly for the job satisfaction that gives, but also for the very pragmatic reason that it helps his/her career. Conversely if too many patients do badly the GMC will take notice and that career could come to an end. If a street cleaner doesn't do the job, sooner or later a supervisor is going to realise it and they can lose the job.
Sadly in all walks of life there are duffers doing their jobs badly who get away with it, often for a long time, but they all run the risk that someone will rumble them, and it does happen. The trouble at senior management level, not just in government quangos, is that all too often the duffers are in a position to cover up their failings, and have somehow got deals where if they're sacked for failure they get paid lots of money to go away. I'm not necessarily saying that this applies to people in BW/CRT, because I don't know, but if I were Richard Parry I'd want to know how Pillings Lock got away with non-payment for so long.
