I just don't get why teachers think they work so much harder than anybody else.
No-one's saying they work harder. Just that they work hard. Lots of people work hard.
Comparing now with then is pointless re when we didn't have and now we do have inset days.
You made this comparison. Both teachers and pupils used to be off on these days. Now, pupils are still off and teachers are in doing training.
The reality is that you as teachers are paid on average a sum equivalent to many others working a 48week year, less public/bank holidays. That equates to ~232 days a year of work. Which is 37 more days than teachers are required to work.
minimum holidays are 25 days including bank holidays - i.e 5 weeks not 4 as a minimum (certainly not average because most people get more than the minimum). Teachers work 40 weeks (12 weeks holiday - the 13th week has already been lost to inset days) compared with a maximum of 47 weeks in other sectors which is (at most) 35 days more than others. This is generous of course, no-one is denying that. It is most definitely a perk of the job.
I would think that that, combined with the minimum 2hours at the end of every single teaching day, should be sufficient to mark, plan, organise your classes, and do the odd training day.
Teachers in scotland have to work an additional, logged 35 hours over the school year - so thats another week off the holiday entitlement (bringing it to 11 weeks/55 days).
I know that the curriculum rolls over, so many lesson plans are rehashed from year to year ( told to me by teachers I know). You are not reinventing the wheel every year.
No it doesn't roll over. Curriculum is always changing. Technology, advances and relevance mean the wheel is developed and improved every year.
I am not sure why you think you should be paid more than your existing full time wage to do a a full time job?
Not sure what you mean by this? Teachers do a full time job as laid out in their contract, and receive a full time salary in return.
