Re: Promotion
Interesting. In my case it was the opposite. No promotion to PSO without "responsibility" which meant managerial responsibility for which there was little scope. Giving evidence that might help convict someone of murder or clear them of the charge wasn't "responsibility".
As it was a specialised skill set with little scope outside they thought they could get away with it. Because I had the opportunity to diversify into IT I managed to escape. The effect of someone contriving that was electric if not unprecedented. The response to my resignation was an almost immediate offer of PSO with no board or any other formalities despite having been yet again refused in the previous year. I'd hoped it would at least have made things easier for others but I later heard it didn't.
