Time for a bit of clarification.
I help out at cubs regularly, but am a parent helper, rather than a warranted leader, and am extremely reliable, on both cub nights and for activities.
Camps are different in that I don't sleep over, the ratios are very good, and I come and go during the weekend because of other commitments (my other child and DH's shifts). I really am just an extra pair of hands, rather than being counted in the ratios and the children are used to seeing me disappear. I would not argue with any leader in front of the children.
I would NEVER ever put the children at risk, EVER.
I usually get on very well with this bloke, but his tosserish tendencies pop out now and again. He can be very smug, and often tells me that volunteers are useful, but he can manage without them if has to. It is an oft-repeated snide remark he makes and is one of the few things he knows that I don't like, but he still keeps making the remarks. I don't expect a round of applause for helping out - I choose to - but I do expect a teeny modicum of respect.
Yes, compo I'm a volunteer, as are all the leaders.
I didn't drop the other leaders in it. He told me to go home - I did what he told me to do. He was half-joking but he has been asked previously not to do it.
The parents know that I'm there on an adhoc basis, so am not relied upon for ratios.
I didn't set a bad example to my or the other children because they were undertaking an activity at the time, so didn't see the spat, and all the children are used to me coming and going.
Thank you for your opinions.
