For every £1 you earn you lose 63p of universal credit so say she took on an extra 10 hours a week at £10 an hour then she would only be around £37 better off a week so would work out at just less than £4 an hour, then she might end up having to pay more council tax as her income has gone up so her council tax reduction has been cut so that 4 pound has become £3 now etc. Would you work in a supermarket for £3 an hour?
This was before universal credit
Which is why I said tax credits.
There are different income limits for each type of tax credit. If you earn over a certain amount, you'll be paid less in tax credits; this is called 'reduction due to salary'. If you claim working tax credit, you can earn up to £6,565 a year – either from being employed or self-employed – and you can receive your maximum payment. If you earn more than this amount, you'll lose 41p of the maximum amount for every extra £1 you earn. So, if you earn £7,565 a year, you'll earn £1,000 extra, which is 41p x 1,000. This means you'll lose £410 from your maximum payment. For child tax credits, the maximum salary is £16,480. If you earn more than that, the amount of child tax credit you'll receive is reduced by 41p for every £1 you earn over this limit. So, if you earn £20,000, you'll earn £3,520 over the threshold (£3,520 x 41p is £1,443.20), which is how much child tax credit you'd lose per year. If you receive both working tax credit and child tax credit, and these deductions apply to you, the maximum amount of each element you receive will be reduced in the following order: working tax credit, excluding any childcare element the childcare element of working tax credit the child elements of child tax credit the family element of child tax credit.

There was a 16 hour and a 30 hour working week limit and if you hit the 30 hour per week you got more. She was on like 22-26 hours iirc and was being offered the difference to hit the 30 hour mark which would have actually seen her far better off as the reduction to tax credits was pretty much pennies.
