One of the numerous teaching unions, the NUT; is holding a ballot of its members to see if they want to hold a one day strike.
This is the sort of approach that we always see in teaching:
When there is a problem, first have a meeting, then get everybody's opinion.
Then do something that is completely ineffectual, but which is designed to make everyone feel like they are making a tough stand and taking firm action.
The main problem in teaching nowadays isn't the money, it's the working conditions. The low status, the mindless paperwork and weak leadership. The constant dumbing down of exams, the stifling PC culture and the fact that there are brilliant and inspiring teachers working alongside utterly useless ones for exactly the same pay. Most importantly of all; the appalling behaviour of so many pupils and their parents, which ruins what should be the best job in the World.
If you want more from your employer, then you either have to convince them that you are worth it, or threaten them sufficiently that they have to capitulate. A one day strike by a minority of teachers does nothing except irritate a few parents.
