I once took pleasure in correcting (in red pen!) a basic spelling mistake on the printed appraisal form my manager had to fill in for me. There were only 4 of us and it was a cosy, collaborative process - yes, it was public sector.
However the biggest waste of time, which probably cost the council a great deal of money, since it was provided by an outside agency, was the 'training' (I use the word loosely) in Health and Safety and Equality/Diversity - every last council employee had to do it.
It was done online, and consisted solely of multiple choice questions, 4 answers per question. If you guessed wrongly, it came up with a cheery, 'Not quite right, try again!'
Each took 20 mins max - it was a complete joke.
But never mind, we were all 'trained'.
