I retired at retirement age, so no resignation lettter.
I received a short letter from the Director-General, thanking me for my contribution of 41 years.
He added that "if there is anything you would like to say about how things were and are in the Office ......... please let me know."
My equally brief reply said that I had been telling the Office for at least 10 years that it was going down the tubes, and not a blind bit of notice was taken.
In those ten years I occupied some big-name desks, so it wasn't just squeakings from the lowest rung of the ladder.
And it went down the tubes.
