The (unpaid - has anyone pointed that out yet?) holidays are key, yes.
I love teaching - really, really enjoy being in the classroom. I don't mind taking work home - I've just spent the last two hours writing an IWB flipchart to talk my year 7s through their recent assessment & showcase photos of some of their work. Three hours this afternoon to mark the assessments I'm feeding back on. No problem with any of that.
I simply couldn't keep it up if I didn't have half an eye on half-term, when I will flop about a la Dying Swan for two days, blitz the house (falls about my ears all term tbh) for a day, do another day's Big Marking Jobs (dh has the Tuesday booked off so he can take the dc out for the day), & then we're off to Whitby for five days - which is our annual family holiday.
Agree with everyone else that my dc don't get nearly enough of my attention in term-time - & certainly no flexibility whatsoever to attend their sports days/school plays etc.
It's a trade-off, & one about which I have no complaints.
Being continually under attack by Slithy Gove, whose qualifications for telling me how to do my job basically amount to being a corrupt Murdoch hack who needs to get his remarkably stupid mug in the papers regularly in order to beat Boris Johnson to the dubious privilege of shoving something pointy in Cameron's back after the next General Election......
...not so keen on that bit.
