Not OP but from my experience with government workers in the UK, who routinely work the same job from leaving school until retirement, their time spent there seems to be inversely proportional to the quality and quantity of their work. If I need something done right I'll try and find some starry-eyed graduate or recent ex private-sector worker to ask. I suppose public work has a habit of being both fulfilling and frustrating, and when that frustration>fulfilment, productivity drops.
