I used to volunteer for guides when I had an office job and had some time to give. The prep was pretty intense and I ended up doing it in my paid job on the sly. Not good.
When I changed sectors to education I realised it was going to be impossible to do both. I would assume that a lot of people who like children and are therefore willing to do voluntary work with them are in the same sector and to be honest, our jobs sprawl into our free time enough were lucky if we get to sleep and eat and keep our houses running let alone anything else. My partner who ran it with me got a job in social services and couldn't commit to the time involved for similar reasons.
I left before guides abandoned safeguarding so I won't go back until that has been resolved. As it is they seem to be doubling down on their idiotic decisions.
I also ran my unit in my own way and ignored all the boring 'wife training' activities. As a result we were popular, but equally I wouldn't want to join in an established group who place emphasis on how to be a 'proper girl' which is so based on stereotypes they welcome males who like sewing over football and ignore the safeguarding implications of claiming to be single sex when they are not.
Similarly I'm an atheist and basically ignored the god part, gritted my teeth through the promises and did rememberable Sundays etc from a non religious pov. I'm not willing to put the kind of religious judgement and pressure I suffered through as an atheist child in the organisation and again, another group might operate that way. I don't think they are truly inclusive as yet because they cling to the old ways.(I mean inclusive in the true sense of the word, not pandering to sexist stereotypes- guides still do that, not sure about scouts).
So basically it comes down to life commitments and unwillingness to push beliefs on children in exchange for providing fun opportunities. Feels a bit culty.
I'm musing with starting my own non religious, non woo organisation when my kids are old enough but again it will depend if I can keep up with the time commitments. It's not a small thing to ask people to volunteer for. I volunteer for local playgroups and the prep and time consuming nature of it is worlds away from scouts and guides, the responsibilities of which could easily be a full time job.
I find it quite astounding that grown adults are deeming others lazy for not volunteering in the cost of living crisis.
