If the government really want to get people back to work, they need to shake up childcare. Heavily subsidised, readily available childcare would transform the number of women able to work full time.
The vast majority of mothers I meet are hindered from working only because of childcare. I've actually met very few women who want to remain at home for the whole of their children's childhood. Most just want to do it for a short stint at the beginning. The trouble is that they can neither find nor afford full-time childcare and we live in a society where state-controlled institutions such as schools and the NHS seem to think that there is always a parent around to do x, y, z during office hours, which does rather interfere with working life unless you can afford an exclusive nanny or have family to help).
Ironically, encouraging people to move where employment is more likely, reduces the chances of parents on low to average salaries being able to juggle parenting with work as they no longer have a support network to help out during INSET days, unexpected illness, Drs appointments, etc.
Government may currently pay up to 70% of childcare costs, but only if you are single and on NMW. Coupled or earning more than that and they'll reduce it and you won't get to the point where you earn enough to not claim anything until you're earning about £30,000 (for two children). £30,000 isn't that much TBH but it's still more than something like 3/4 of the population and certainly won't pay a nanny.
If the state subsidised childcare the knock-on effects of so many more people in work, spending their earnings, would more than pay for it.
Although it does rather rely on there being jobs for all these emancipated, work-hungry women to go to... 
And doesn't take into consideration at all about the fact that small children need looking after and is it really that off the wall that 
their own parent might want to do it.
