Alex Ferguson claims he used his notorious hairdryer treatment no
more than 6 or 7 times in his long and successful career. The accounts
of former players would indicate it was a lot more but may be the
truth is that it was used sparingly in order to maximise its impact.
The point is All his players had heard of and probably witnessed one
of these fearsome verbal assaults. No one wanted to be the subject of one.
Showing your staff you’re annoyed Is not necessarily a bad
thing. I worked in the care industry with vulnerable adults and some
times I witness or learnt of staff behaving in a callus and cruel way
or simply doing what was easiest for them irrespective of the
individuals wishes and needs. On such occasions I would make it clear
this was totally unacceptable. I may have raised my voice but I never
gave the impression I had totally lost control. The aim was not to
make people afraid of my displeasure but to realise how unacceptable
there behaviour was to me.
