DynamoKev this reminds me of the time, many years ago, that my late DM went for the next grade up in her job, didn't get the promotion (married woman with DC was the reason , I suspect).
She miffed but accepted it, until they brought in a younger male to, in effect, become her boss - once she had "shown him the ropes".
Why on earth they seriously thought she would happily train a newbie to be her boss at a higher salary than hers, is beyond me. She was polite but vague when asked to provide in-house training.
This happened to me, brought a man to a newly invented position on twice my salary. What we did was niche, exporting, currency movements, letters of credit etc, his expertise was in finance for selling cars in the UK.
Every time one of the sales team came in our office, I grabbed my fags and went for a smoke outside, he'd join me on the step wanting me to tell him what to do.
He lasted 6 months, I was then offered his job, his salary plus 10%.
