I do admit to a little sympathy with Cantleave's opinion, but I would point out that P.S workers contribute a large percentage of their wage toward their pension.
(lets not get in to an argument about the details).
What the strike is mainly about is the injustice of the Government changing the goal posts for those already in the scheme, for which they may have signed up years ago, now to be told they must pay more in , work more years before receiving it, and when they do get it, it will be less than it should be.
I have no axe to grind on this, I worked in the private sector, and as a JW was not encouraged to think about providing for retirement, hence I now have trouble scraping together my beer money !
