"de-skilling, as characterised, for instance, by the micro-managing lesson/unit plans, constant changing of standards, use of unqualified staff."
Is not something that I recognise in my profession. For starters, in all professions there are changes in standards of delivery over time, medicine, law etc. For instance, Junior doctors are about to go out on strike on changes to their working standards aren't they.
Micro-managing of lesson plans? I am really experienced and have been in lots of schools, I've never been told that I have to deliver something in a certain way. I have autonomy, as do my colleagues, over how I deliver my lessons successfully to the students in the room. I plan my lessons based on their abilities, strengths, weaknesses and differentiate accordingly. I see no micro-managment.
The use of unqualified staff has been majorly objected to by virtually all teachers groups and by many schools, but "unqaulified" is a misleading term. Those that are hired will have a relevant degree in the subject they are required to teach, and are required to undertake professional training whilst working, they are also supervised by people with QTS throughout the period in which they are training.
The GTC was formed by act of parliament, but so was the BMC, the Law society is a much more ancient body formed to protect the vested interests of lawyers. The GTC was abolished by Gove, and actually by many in the profession that was lamented.
Gosh, why am I actually replying? Must write out a hundred times, I must not rise to the bait.
