Seems a bit odd, him asking now? I would ask him why - are they not as comfortably off as she believes? Is he trying to make her more independent? One wonders why?
BUT assuming YOU think it's a good idea:
Sign on - you get six month's NI paid, probably no money, but worth filling in forms. (Hopefully you have already seen all the publicity about back claiming for child rearing NI contributions)
You will get help then from someone with your CV
They may guide you to a volunteer role, but if not look at local opportunities (Guides and Scouts for example will give you some training)
OR go to your local FE college to see what vocational training or short courses they can offer - as you are unemployed some of these will be free.
On-line there are a number of things like Alison.com, who offer a wide range of free courses - have a look through their list to see if anything interests you. Start perhaps with one of these alison.com/tag/confidence
Your CV - I am SURE that you have done other things than just keep house, so write yourself a list of the things you have done for and with your children (PTA, sport club) and the skills you gained (organisation, marketing,???. clearly you have computer skills ( if you wish to hone them there are online free excel courses for example) There is a post and conversation here about contents of CV for returners.
What did you do for the 10 years or so before the children? Education, training?
Would your previous employer, if still around, have an opportunity for you?
What interests you?
- gardening? - your local garden centre might need you
- reading? - start by volunteering at your local primary school, the admin, reception and assistant roles are often offered to volunteers in preference to unknown applicants
- knitting/sewing? - you could start your own repair business
- baking? your local baker's might value you you as a sandwich maker, or you could try doing your own business
- No? then Tesco, B&Q and John Lewis are known to offer part-time short week hours for older applicants.
- have you thought about casual? - I am an exams invigilator which gives me regular training. I am also an elections poll clerk - this gives me perhaps 5 weeks'work a year. My friend is clerk to the governors, clerk to her town council, AND a local hunt group which total part-time leaving her some weeks free to catch up on things.
Get a health MOT from the doc and your vaccinations up to date too. And tell hubby that you will need a new outfit and shoes for this.
Good luck
