But you're looking at time outside the house, which is fair enough, but if you look at time actually on the pitch, it is fair recognition. I suppose it just depends on which way you look at it, but currently as a 3, I'm outside the house for approx 6-7 hours, collecting £65+ mileage (and the mileage compensation is more than fair at 40p, although appreciate it is to pay for wear and tear also).
If you look at time outside the house, I'm getting under minimum wage, but if you look at what I'm actually being paid for in terms of refereeing a football match that lasts 2 hours from start to finish, I'm on £32.50 an hour. Big difference.
I don't expect work to pay me from when I leave the house, so football is unlikely to do so also. I also find refereeing far more enjoyable than my day job so I'd willingly take considerably less to do it. I meet a colleague usually a short while after leaving the house, we have a good chat and a laugh on the way to the match etc. It's not really 'work'.
Edit to add: You're entitled to look at it however you wish, but personally, as football is only a bonus on top of my day job income, I'm more than happy to accept less per hour out the house to referee a better standard of football and be better looked after, have a good day out with a team of 3 etc.
