I think without want to be too presumptuous, we all but agree on this. I would not expect a referee to be dropped for making a few minor or even one or two major errors any more than I would a player that would be unrealistic not to say unfair. I would however expect this to be noted by the powers that be and no doubt it is and dealt with accordingly and as is the case with a player, kept in the dressing room.
If however a player keeps making similar mistakes or for that matter anyone in any business, they are “retrained” and whilst being retrained taken from the work face to concentrate on improving their performance i.e. dropped. This does not in my opinion appear to be the case with referees, which is again in my opinion very unusual.

I have no evidence but would be amazed if there wasn't weekly review of referee pperformance & regular training/retraining. There just isn't a pool of full time & good enough refs large enough to drop them regularly. The same with most squads; unless you are the Warrington of this world there is not much quality waiting for their chance on the bench.

I might be wrong, but Child strikes me as being from the SCummings school of refereeing. If he is not the centre of attention, then he will do something to make sure he is.
