Teacher's Strike: Just a thought . . .

Here's a thought . . .
How much is the planned strike action for tomorrow really about the pension rights of Public Sector workers such as teachers, and how much is really about the Unions wanting to flex their muscles and challenge the government?
.
The problem is that for anyone whose memory stretches back far enough, this has all the same ingredients of similar actions in the past that were primarily about Unions trying to prove that they were in charge, and using the aspirations of the workers as cannon fodder.
.
How easy it is for overpaid Union bosses with their expenses accounts on top of their high salaries, and their gilt-edged pension pots, to call their members out rather than  negotiating around the table. 
.
As I said, just a thought . . .
