You realise that £24k as a 0.7 is £34k FTE.... then if you make that a 48 week equivalent it’s £43k...
Ok, I'm going to bite with this one...
Let's take a fairly middle-of-the-road FT contracted hours of 37.5 per week. 70% of this is 26.25 hours.
Take off the 15 hours in the classroom, that leaves 11.25.
Looking at the 'average' week in our annual school calendar, an hour a week is spent in meetings/parent consultation meetings and 15 minutes is spent on statutory break duties. That leaves 10 hours.
I'm going to assume 'lazy teacher mode' and not plan any lessons from scratch. I'm going to use last year's PowerPoint and last year's worksheets and get them photocopied. I can't be arsed to refresh my knowledge of A level stuff so I'm going to wing it off the top of my head and teach it like I did last year. I've taught for 13 years and have the definition of first ionisation energy tattooed in my brain anyway so why waste time. OK, I haven't taught year 8 biology for 9 years, but who cares? I can just bluff it. We'll allow 10 minutes per lesson planning time in order that I can grab the bottles off the shelf in the prep room because I haven't bothered to order stuff in advance from the technician. That's 2.5 hours. That leaves 7.5 hours.
Teaching 7 classes means that, on average, at least one class per week is doing some sort of test or assessed task. If I get the kids to mark each others' and then just cross-check it can take 2 hours but a full-on year 13 exam may take 5 hours to mark. I've got to sit there with a calculator and try to pick up all those 'error carried forward' marks after all. Let's 'average it out' at 3 hours. That leaves 4.5 hours.
As a lazy teacher I'm going to cut every corner with respect to emails. Anything abotu CPD opportunities or 'teaching strtegies' I'm going to delete without reading. I'm only going to respond to emails from the head teacher or something I deem 'important enough'. I could cut time on that down to 2 hours a week. Sod all those emails from HOY that say 'I'm meeting with Tarquin in 7A's parents on Monday to discuss his current progress. Has his homework improved since last term?' Tarquin has 11 teachers so the HOY won't notice if one teacher doesn't respond. Same with the Annual Review for Students with Statements return forms. That leaves 2.5 hours.
Assessment/Data input deadlines cannot be missed. 7 classes means 21 reports over the year.Cutting every corner possible and just 'copying and pasting' statements from last year means I can probably spend 2.5 hours on each class report. That's a lot of corner-cutting. We'll call it 1.5 hours per week on average over the year. That leaves 1 hour.....
Notice all the things I haven't done:
I haven't marked a single exercise book. Not one. I teach 160 students.
I haven't planned a singles lesson properly. No forward reading, no allowance for new specifications, no differentiation, no real thought, no consideration for time of day or prior learning.
Intervention for under-performing students? No, none at all.
I have left every lab at the end of the lesson as an utter shit-tip. I haven't had time to deal with any broken equipment or help tidy up chemicals. That's what the technician's there for isn't it?
Follow up on any behaviour issues. So, Tarquin hasn't done his homework again? Sod the lunchtime catch-up session - I've got a copy of TES Jobs to leaf through in the staff room.
If that's how I carried out my duties as a teacher I could quite legitimately be sacked for incompetence. That's the reality of it. A competent teacher 70% can, at a minimum, complete their hours in a 37.5 hour working week.
Oh, and teachers work 39 weeks, not 38 (it's called Inset).
A full-time 'normal' worker does not work 48 weeks a year. Many employers (and I mean many) offer 25 days plus bank holidays. Remember, 6 bank holidays fall within teacher's precious 13 weeks. So, many people with 'full time' jobs work 46 weeks.
So, a FTE salary for a 0.7 M6 teacher with London fringe actually works out to be £28,300. Doesn't sound quite so attractive now, does it?
