A former colleague told of when he left his previous company...

He had worked a lot of extra hours and accumulated a lot of time off in lieu of payment. One day he went to his boss and said he was leaving.

"You are on three months notice" he was told.

"Fine. I've got 3 months time instead of pay. I'll clear my desk and say goodbye."

And off he went, taking his 3 months as paid holiday.
