Even with 4 DC, the only reason I wouldn't be better off in work is because of childcare costs. If childcare was more subsidised, then you would find a lot more Lone Parents would flock out to work.
Most people I know that zDON'T work say it is only the childcare costs that cause them to be worse off while working. They could afford to pay a nominal amount when they are earning LESS THAN A LIVING WAGE, but Nursery fees here are £52 a day, and a days care for a school age DC in the holidays is £50. Which is not particularly helpful when you only earn £47 a day...
Yes, Tax Credits pay UP TO £210 a week to help with childcare, but if you have more than 2 DC in childcare, with one in Nursery, that covers less than 60% of the costs, and the more DC you have, the lower the percentage of the costs of childcare is covered by that £210 a week.
These are people who were either SAHM's or working very short hours around their Ex's job while they were IN a relationship, and had their DC's as a joint decision, but have been left to bear the ENTIRE costs of childcare without their Ex's being made to pay towards it.
If the rich fathers that leave are forced to continue to pay private school fees, why is it that lower income fathers are not made to pay half the cost of childcare fees when they leave their relationships?
Making fathers 50% liable for childcare fees when a relationship breaks down would get ALL the single mums I know that are on benefits with 3+ DC's back into employment.
As far as I see it, despite fathers supposedly being 50% responsible for their DC, they are not expected to be 50% responsible for essential costs such as childcare to enable BOTH parents to work.
Any changes in the benefits system IMO should have addressed this, and made it possible to split claims in respect of shared care, for both the RP and the NRP to claim help with the childcare costs if they were separated, if their income was low enough, so that both could become liable for 50% of childcare costs that enable them BOTH to be employed. Why is it deemed to be solely the financial responsibility of the RP, when their income has to take a hit anyway as they are the ones who have to fit their work around the available childcare. Leaving them unable to be as flexible about employment hours and days as the NRP anyway.
And it would certainly focus serial Father's minds when they walked out on their DC if they KNEW they would be liable for 50% of childcare costs if their child's mother/s went back to work. And none of this taking it out of JSA at a stupidly low rate of £5/£10 a week - if there was no protection on the possibility that they could lose ALL their JSA to pay for their child to be cared for while the child's MOTHER went back to work, they'd soon take A job, ANY job...
