English teacher from England. Currently teaching in South East Asia.
Improving teachers working conditions will attract and retain a better quality of employee. It will improve teachers’ performance by allowing talented staff to thrive, rather than only allowing untouchable, dog eat dog, spin doctor type teachers to survive. You could even argue that success as a teacher simply happens at random, through being lucky enough to avoid being bullied by nothing more than chance.
There is a definite attempt to come down harder on teachers in order to raise performance. This will actually achieve the opposite, making working conditions worse, which will in turn make more talented staff leave, or never join in the first place. This will over time erode performance and mean more and more teachers are not up to standard.
