What they should with him:-

One day you serve him up a couple of hot steaming turds on a plate.

You say eat those, and if you do that every day for five years - you can go free.

Trust me on this one, I had a job with exactly those terms and conditions - and I promise you - he won't like it. After about two years, you wake up every morning wondering if today's the day you'll do yourself in.

After five years, you say well done! We extended your contract.
