Just playing devils advocate here - there might be a reason Charlotte isn't working at the moment. I'd imagine she probably helps Donna a fair bit. Also, I wonder how easy it would be for her to keep a job, she doesn't seem to have much of a support network around her, so if one of the girls was poorly and had to stay off nursery/got sent home etc, I'd imagine Charlotte wouldn't have many people who would be able to help her out and have the girls. I very much doubt Donna would be able to help so that Charlotte can work as she's poorly herself. Many employers wouldn't put up with too many sickness days, especially if it's because of childcare issues. They'd expect the employee to sort something out. Also, Charlotte hasn't worked before has she? She might struggle to find much dependant on her qualifications, something to suit nursery hours etc. Lets be honest as well, she'd be unlikely to get a part time job that paid much. I know people shouldn't just rely on benefits, and I am in no way condoning it, but sometimes people get trapped because the system pays them more money than they'd ever get working. It's clear she doesn't have loads of money as it is, so she might have to take a cut if she got a job. Sometimes, as much as people don't agree with it, it really is just easier for people to stay off work until their kids go to school and I think for Charlotte that might be the case.
