Size of packet not what counts
As a member of the endangered species, I can truly say that I love my job and cannot think of any other that would be as fun or rewarding. I am, however, very sceptical about the narrow way in which a school's success is now measured and the plethora of tracking grids and assessment ladders that accompanies this. This, together with some of the more restrictive health and safety regulations, means that many very able men simply feel too constrained, which is a great loss to the profession.
Job satisfaction means more to most people than simply the size of their wage packet.
