I have an idea and I'm not sure if anyone would be interested, or if it's potentially not even legal. 
Just wondering what you would think if your organization was approached with this proposition!
So my eldest is eleven and I've not been able to work since they was born due to the expense of having multiple children in child care. Prior to having my children, I had a fairly piecemeal CV as I traveled and moved around a lot. I was studying but that's been fucked by covid, I don't want to make myself too identifiable but it really isn't an option financially now, so please don't focus on that.
Basically, I need a job to get some real experience and start building a CV, and also to eventually have some sort of career. But I also have to do it around the school day or be paid enough to pay for childcare and not be paying for the privilege of me being employed.
I'm really interested in working for a woman's charity in some capacity. I'm not too fussed about the specifics though, I'd just like to feel like I have a bit of meaningful employment iyswim. So admin, or directly doesn't matter to me.
I was wondering about approaching a few and offering to work for free. Either I could set myself up as self-employed and basically charge them enough to cover national insurance contributions or they could even employ me and I donate the net income back after deductions have been made? I think both options would be legal right? I appreciate it might sound a bit mad though and they might not be interested. The thing is they'd basically get a free part time or nearly full time employee. I'd get some training. I could do 20 hours somewhere while children are at school. And could even do more at home on the computer etc once I've collected the kids. I'm an immigrant and want to pay NI contributions so I can start working towards citiznship, so I really need a "real" job not just a voluntary option.
