I assume those who have posted that working or working more hours 'is an option' are aware that many, if not a majority, of people on UC are WORKING - many full time! Eventually, everyone who currently gets Child Tax Credits or Working Tax credits (you know, to pay for the childcare they need to be able to work, etc.) will be moved onto UC. The problem is low wages.
Yes, your employer won't pay you more if you have a third child. But until this change, you could claim additional Child Tax Credit/Working Tax Credit plus Child Benefit - this also helped women stay in work instead of having to give up/go part time/have an abortion. If you were on FT minimum wage and your baby was in nursery full time, that's hundreds of pounds each month you've potentially lost out on.
It's not just 'feckless benefit scroungers'
that have been impacted by this policy!
I had a pregnancy scare after this change came in. I took the MAP after a contraceptive failure then my period didn't arrive for weeks. I was terrified as I knew there was no way I could now manage with a 3rd child - I was working FT btw and would have been able to just about cope before - not live the high life, but just about cope. I would 100% have had an abortion, even though it would have seriously affected my mental health, in this circumstance. Luckily, I wasn't pregnant.
As far telling those parents who can't work or can't work more hours, due to disabled children or caring for elderly parents, to just 'stop shagging' for the rest of their reproductive lives... I have no words
