Bit unfair, as I haven't stated anyone is inefficient.
However, since starting teaching I've been concerned by competitive stress and exhaustion and the constant insinuation, as evidenced in some of the posts here, that if you aren't working every hour God sends, exhausted, stressed and overworked, you're either not doing your job properly or you are some sort of cold superhuman.
That has a damaging effect because it makes every teacher think along the lines of 'more work means good work' (not always true) and 'if I am not doing X number of hours, I'm missing something' which also isn't true.
It's true that the examination syllabuses have changed, but the basic fundamentals of good teaching haven't and nor has the essence of the subject. English language and English literature are, after all, still English language and English literature - it isn't as if somebody has asked me to teach German literature or something! It isn't going to take me six weeks to read a novel or play I might not be as familiar with as in previous years and prepare some stuff on it.
We are all different. I don't think anybody is 'inefficient'; they obviously work differently to me, but I hate the assumption that all teachers work seventy hours plus a week and throughout the holidays and have no life. It's off putting to new teachers in the profession and it also just isn't believed by chunks of the population. I think people believe SOME teachers do but it's misleading to claim ALL do.
