I have come to learn the lower paid people often work the hardest. My role now is over double the pay and half of the work and it seems similar for everyone senior in my org.
Yeah, it took me 30 years to realise that this is the case for some jobs. My theory is that once you get to a certain level of quite specific skills and knowledge in some sectors it's quite easyt to pull the wool over other colleagues' eyes about what you're actually doing, because most people won't understand what it is that you do. Working from home has enabled that to happen more easily in my view. Basically for SOME roles, it's easy to "big up" the importance of your role and why your large salary is justified.
It's impossible to do that if you're senior or professionallly qualified in other sectors. eg. a hospital consultant, or even a junior doctor. Or a head teacher, or even a normal teacher. A pilot. You can't blag or hide anything and if you slack off AT ALL, all the shit hits the fan and it's your head on the block and often the heads of other people too. You do long shifts, work in your own time, at weekends, evenings, double shifts etc.
And of course, there are people who are MUCH less well paid, at really junior grades who work their assess off for very little money and if they cocked up it would still have major repercussions, even though they're at a much lower grade.
Education and health are the 2 sectors I'm thinking of where every single role matters, everything you do matters and every minute matters.
