The "managers" that everyone is getting their knickers in a twist about are not the demons here. They are employees like anyone else, often ex engineers themselves, and just as vulnerable and fed up as anyone else.
They are not the ones dictating that resource pools are reduced, that pensions are made worse, that expenses are locked down, that suppliers aren't paid, that training is none existent, that pay rises are a thing of the past, that bonuses are awarded to only the very few. They are merely the ones trying to continue to run and resource a service in the face of all of those factors.
Blame your mythical "management leeches" if you wish, that's what the likes of Lawrie want you to do. Perhaps he should do what you all want and sack them all. Then let's see who does their best to watch your backs or protect you from some of the ridiculous demands of you all that are placed upon them.
For God's sake grow up and see where the problem really emanates from here!
