Luckyoldbeethoven There have been many unfairnesses and inequalities in the pension system that are gradually being removed. In the 1960s, if you worked for a company for less than 5 years, when you left, they just returned your cash, until 1990s (I think) if you worked part-time you couldn't pay into a company pension scheme. I 'lost' 12 years of occupational pension through those.
The one that had me shaking with anger, even though the amount was small, In the 1960s I worked for a company that gave staff personal pension schemes, so when I left, after 2 years, I was given a certificate to say that I was entitled to £10 a year pension (1968 values ), nearer £100 in current values. But at that point such pensions were frozen and fixed. So, although the insurance company concerned had my pension money invested for 35 years when I reached 60, it was still worth only £10 a year, or £162 after tax. I must have paid more than £162 into the fund at 1968 values, probably £2000 plus in current values.
A few years later the law was changed so that you got the capital appreciation and annual interest the money accrued, but too late for me.
