I was once told "whatever you do dont be good at your job or you will never get promoted"....and to some extent its true because your boss is covering his own **** and if he needs you he wont be putting you forwards for promotion. British Steel was a real mess as they introduced a system of benchmarking to compare one job against another and one pay cheque against another.....they succeeded in making the chief of the cleaners one of the highest paid men in the company....In my experience its usually the stupid people promoted in good jobs. An idiot i worked with years ago drilled a hole through the palm of his hand, a few weeks later he had a cushy "Managerial" job, probably counting paper clips.
