Redliner,
Without doing a search, I believe H23 was with CX for 6 years which means he joined during a period when housing was relatively low in price. Probably bought a place and made a fortune.
Therefore, what you have to realise is that the "money bucket" got filled first with H23 and he now has the option to go elsewhere! You fill that money bucket up and that other bucket gets pretty small and soon it's full too!
He's fed up and that's fine, I'm getting close to that point too! It doesn't mean the job is unbearable just not perfect. But then, which job is?
