I'm a teacher near the top of the main scale with a (small) management point, so in other words respectable pay. Money is tight though, plus working 3 days isn't great for professional development so I thought I'd pick up a 4th day. I've just calculated that certain months the extra childcare would be MORE than the extra pay, depending on how days fall that month. This taking into account tax, childcare vouchers etc.
It seems like madness that with a very decent job it's still not work my while to work. Many of my friends are in the position were they simply can't afford to work, with ONE child of nursery age. It feels a bit like the balance has gone.
