I quit full time primary teaching in 2000. Nowt but supply, maybe a short maternity leave or nervous breakdown cover etc now. Get the good schools, do a good job regarding classroom management and you pick and choose.
I do fancy a clean break but as my only qualification is an Outdoor Ed degree and I am 54 with aches and pains, I don’t see that taking me far. Supply can be fine once you get your self well known.
