>>> Anyone have a job where you can't shut off after a fixed amount of hours each day otherwise you wouldn't get tasks completed / projects completed that's on going . . . . You don't get paid any extra . Your salary is a fixed amount irrespective of how many hours you work.
I had a job like that for 15 years, where I never worked fewer than 60 hours per week and sometimes exceeded 80 hours. It was also a job where I was sometimes expected to attend courses, with no extra pay, in my own time. It was secondary school teaching! ((I was fortunate though, I had to work far less hard than many of my friends in primary teaching did).
In one case I was told that, because my colleague was on maternity leave, I'd have to change my holiday plans, and attend a training course in the Easter holidays without pay, so that I could qualify as the school's mathematics assessor for the exam board. (Otherwise there would have been nobody able to award a GCSE-equivalent pass grade to some of our less able students).
When I kicked up a fuss that there were no qualified first-aiders in our school, I was 'encouraged' to attend weekly evening first aid classes (i.e. in my own time) to gain a qualification. I was then billed £200 (which was a lot of money around 1980!) for the privilege of doing so. I eventually managed to get my employer to foot the bill but I was then placed in charge of first aid in the school, with a lot more responsibility but with no extra pay, for the next decade. However I wasn't given a budget for first aid supplies, so I ended up buying loads of sticking plasters, bandages, etc out of my own pocket.
