The average teacher turns up for work about 190 times a year. On Wednesday, they withdrew approx 1/190th of their annual labour.
They will be docked 1/365th of their salary as a result. This effectively means they lose close to half a days pay.
And I'm not even going there with the amount of sick leave and training courses and days off during exam times and sticking a video on for the kids whilst snoozing in the staff room and 9-3 days with an hours lunch break and 'free' periods and so on.
There were a lot of public sector workers on strike on Wednesday that had a strong case. Teachers didn't. They are hugely over rewardied for the job that they do.
