@Vern - I see where you're coming from now. I must admit, that I've had a completely different experience this side of the pond. The state system, while not perfect, insists that its teachers are members of a body that ensures minimum standards, codes of conduct etc. Indeed a percentage of our salary goes to pay for our membership.
Good teachers are rewarded through promotion and the award of responsibility points, so they generally earn more than those who don't show as much 'go-get' or ambition anyway. Of course, there are always those who talk a good talk, and I'm sure there are many disgruntled teachers in many schools who believe that they deserved the promotion as opposed to their colleague, but that's human nature, not necessarily anything to do with performance.
BTW The 'ultra-right' nation was a jab. ;)
