A really interesting blog here that I'd not really considered before, despite being a part time teacher (just over 0.6)
We see all the figures about how half of teachers leave within 5 years (the lesser figure quoted is those who start teaching and doesn't include those who drop out of training, I think), but nothing is ever mentioned about the huge numbers of teachers who have to go part time just to keep their heads above water.
I went part time after my first maternity leave. My second child will be starting school next year and people have started asking whether I'll be going back full time. The honest answer is that I can't imagine ever going back full time. And the kicker is that my school doesn't allow part timers to have TLRs which means that my career will effectively stall at the top of the upper pay scale.
