Surely that department isn’t a one man operation and the club owns the data not the individual.If you lose the person who knows where all the data is, then it's almost like losing all your passwords. Good luck. 20 years of organizational knowledge leaving any organization doesn't get replaced.
If this is the only poaching Hardwick does then I think the club will be pretty happy. If it’s the thin edge of the wedge, well that’s another story.
