I support the teachers and can quite understand why they went out on strike. If it is such a cushy number, why do so many leave after a few years?
I spent most of my working life as a legal secretary, for which I was well paid and, at least in London, had fantastic benefits (including 6 weeks holiday, thorough annual health checks, heavily subsidised restaurant, etc., etc.). I re-trained as an adult literacy teacher in my latter years of working, and, though I enjoyed it immensely, I just could not afford - energy-wise, money-wise and health-wise - to continue. I found that, with all the hours put in preparing: lesson plans, lesson material (and photocopying it), termly schedules, student profiles, individual learning plans, sessional progress sheets, end of term reports, etc., etc., etc., I was working full-time hours for part-time pay. I reluctantly returned to secretarial work.
Having now retired, I'm doing voluntary work in a school and I am full of admiration for the teachers there. If a teacher is conscientious (and I feel sure that most of them are), it is a very responsible and demanding job and one in which they seem to be under constant attack.
