I keep on referring to a metaphorical 21 Yr old because why would an employer pick a 32 Yr old with the same qualifications and responsibilities for 2 kids over someone free and easy with no responsibilities?
The only argument is for 'life experience' but in the OPs case she devoted her recent life, by that I mean most of her working life so far, to bearing 2 children and part time shop work. Before that she wasn't a professional in anything because even today she isn't a professional in anything...
She has no real life skills relevant to say, an accountancy office. Yes, mummy skills.. But again, irrelevant.
99% of employers will go for the youngster, the metaphorical youngster. With straight As, a 2.1 or 1st, and no child care responsibilities.
Even if the OP gets a 1st grad job, it'll barely pay more than minimum wage, so if she can't as she says afford childcare for 2 now on a nanny wage, she won't be any better off on a grad wage... So she won't afford childcare then, either.
Accountancy firms understand not everyone has had the same chances in life, yes, but the OP did badly at a level, had kids young, made her choices.... Harsh, but they'll go for the youngster.... (who also deserves the chance from the 100 applicants)
God, when was student loan debt nothing to worry about. If the govt can change the interest rates and different deals, they can one day find a way to make people to pay it back on death... Ah, a student loan inheritance tax!!! It's only a matter of time if only 50% pay The debts back....
You think your children will inherit your home on death, er nooooo... Not any more. Mummy owes £100,000...
God we are naive in the UK. The goalposts can be changed at the swish of a new policy and new government.
