Many thanks for the replies, very much value others opinions.
I agree that £5 isn't enough and its deliberate really! She used to get £8 a week, and for that she was expected to do one or two basic chores, but she was very upset with that arrangement, as she doesn't see why she should do chores for 'nothing'. She was a nightmare. I know, I know. Bear in mind that she has an autistic sister that can't do what she can. So with her agreement we reduced it to £5 per week, and any more money she wanted, she could earn herself by choosing chores from the list. One example is wash and clean my small car for £10. She did it once but decided it wasn't worth the effort for £10. Her sisters pocket money was reduced too to make it fair, and she never even complained.
She also gets £30 per month clothing allowance, and I pay half of her phone contract.
She has until 1st Feb to get a job (she agreed in November she would get one, there are loads round here and all her friends have jobs), or I will be getting her a volunteering job. She has done absolutely nothing to get one, even though I have been pro active and been out sussing them out for her. I have already found her a volunteering position if need be.
Yes she goes out to parties, she drinks, but never takes her own, she smokes I think, but again, won't buy her own. She owes me for Xmas still, so no pocket money til Feb, although she could do jobs to repay quicker. the clothing allowance will still stand.
The bottom line is, she is a lazy girl, I mean really lazy. Her sister works for 9 or 10 hours volunteering every Sunday without fail, getting her hands mucky, getting cold and messing with animals, but she says that doesn't count as she enjoys it!!
Her sister also does dog walks for people who are elderly etc, sometimes they pay her, sometimes they don't, but again even though she's doing something, it doesn't count as she enjoys it!!
