These pensions are not available in the private sector now so comparisions do not apply.

I went to school in the 60's when there were no strikes and good school dinners which about 98% of pupils took advantage of.
Most of the teachers had fought in the war and would have believed strikers should be put up against a wall and shot.

All these unions ranting about negotiations. Private sector companies just said this is what is happening move to another company if you do not like it.
