I work in the private sector (I am educated and work in a manufacturing environment for a large successful mutli-national company) and when I signed up to my pension it was a very nice defined benefit, final salary pension.
Our pension fund could no longer afford this, so we are now paying more, for less money (defined contribution) and retiring later. Its not what I signed up for, but if the pension fund cannot afford it there has to be changes (money cant appear from nowhere!).
It is unlikely I will be able to do the job I am doing now (stress/regularily working from home unpaid when ds is in bed to catch up) when I am in my sixties and will need to career change before I retire (probably earning signifcantly less).
Most people I know in the private sector have had similar changes over the last few years.
Our manufacturing site has negotiated 3 year pay rise deals with the unions (made in good faith at the time) that have had to be retracted due unforeseen changes in business/economy which make them no longer affordable.
Most people I know in the private sector have had no or pitiful pay rises in the last 5-ish years (as companies cannot afford increases due to their increasing costs - including pension contributions).
Most people I know, due to increasing outgoings costs have a lower standard of living than they did before (struggle to have annual family holidays etc).
Genuine question : As we all have the choice to stay or leave our jobs/professions if we think we can get a better deal elsewhere, and ignoring all of above reasons as they relate closely to the private sector too - why is the public sector pensions any different in their contributions/benefits needing to be changed so their funds can afford it?
