Serious, this has come up? I work in education, but to say the old "6 weeks and another holiday" is just pure crap. The amount of time and effort that has to be put in to teach the younger generations is ridiculous. Meetings, lesson planning, marking, report writing and not to forget actually teaching the students, it equates to a silly amount of hours. I don't think anyone can comment on it until they actually have, or know someone that has, taught full time for a number of years.
Regarding INSET days, they are decided by the LEA (or county council), and they are normally held at the beginning of a new term, but it can vary. I would challenge anyone to do a teacher's job to see how they can manage it.
As school starts at 9am and finishes at 3pm does that not leave some time before and plenty of time after to have meeting, prep (it hasn't changed that much from previous year or class) Marking and report writing, the actual teaching is done between 9 and 3 with time off for lunch.
The point I'm trying -badly- to get across is it's a job, and all of us in our jobs have to do many hours over our official 9-5 but without all the INSET (apologies) days and extra holidays which do seem to come every 6 weeks so it's a tad harsh to say we're talking crap!
No-one is saying it's an easy job but it's a job nonetheless and could be managed within the normal working time frame.
P.S when did it change to 9-3, it was always 9-4pm when I was a lad riding to school on me bike then getting the Hovis on the way home before a bath in front of the fire, a cold potatoe then sent to bed...Luxury!
