What a daft comment, people move jobs when better offers come up and when their current one is stale. You may be eternally happy in your job and love your employer but in the real world it is a rarity.
As it happens working 24/7 caring for my mrs is the most rewarding job I've had along with the worst pay.
Why such a daft comment? Footballers have tantrums to get their own way is exactly the same as a 6 yeast olds IMO. He wants to play in the prem? For starters try at least hitting the target from 12 yards.
