I've just checked his Linkdin. He did 5 years. Just as the salary starts to ramp up he resigned after apparently being injured and becoming disillusioned. He left an extremely secure job (Police can't be made redundant) and if you're out your 2 years it's hard to get rid of you for other reasons. If you are injured on duty (he claims to have been), they are extremely supportive with unlimited FULL sick pay, 33 days holiday, guaranteed overtime if you want it, to set up in an MLM so forgoing all that, and in doing so also leaves one of the best pensions around (although would have been paying 9% for it).
He then states that within 6 months he was earning 4x his salary. So 4x35k+London Weighting...... if he'd stayed in and didn't climb the ranks he'd be on 41k+London Weighting basic. Bet he's not earning that now, WITHOUT all the benefits the job brings.....
