To be honest I would have thought all the rules are common sense: 'don't bet on your club', 'don't bet on competitions your club is involved in', 'don't get involved in match fixing'.....
If you really need to gamble, surely it isn't difficult to find something else to bet on. Anything else at all would do. Surely it's not worth your job??
