Your response of they are generally seasonal only relates to one of the examples I put forth. Also I look around at those close to me that are doing all of those things, other than the brick layer, and no, very few are in the physical shape to do these jobs. I certainly am not, nor the guy I'm currently working with and his bad knees, or 90% of our overweight maintenance guys or the ones who have various non-visible ailments. But all we as a society do now is take one particular selection of people and virtue signal our outrage over what they are going through. First it was the poor fast food, restaurant, and grocery store workers who were out there risking their lives to provide your essentials. What about those who risked their lives and couldn't stay home because you (general population you) wanted fancy new clothes or wanted to build a new patio while you were off, or bought a new car, furniture, and multitude of other things that everyone was out mingling with everyone else more than normal at a time they were screaming for everyone to stay home? Why only the restaurant owners then. Why only the medical workers now? Who cares about the restaurant workers now? I don't know a single person who was out of work for more than 3 weeks, every person I know were risking their lives going to work and not a single one of those people were doing anything "essential" as the narrative was.
You are correct about society and how they react to things. The only people I personally know who were out of work for any amount of time other than restaurant employees were those who have chosen to be. Everyone else I know was back to work or just never stopped. Heck, my kid tested positive for covid last week, but I'm required to come to work anyway. People here are burned out from working 6 12 hr shifts a week to keep their co workers safe. Personally I've never been outraged over any of the poor essential workers out there and I am one of them. Even if every single non essential place had closed, there still would have been hundreds of thousands of ppl who were working in hospitals and prisons etc, who couldn't stay home. I really didn't get the outrage over any of it.
Why do people choose to do a job they are physically not in the shape to do? I'm not trying to be snarky, I just don't understand it. I wouldn't work where I work if I couldn't handle it 40 hrs a week. Especially right now when there are many other jobs out there.
I suppose when I think of the types of jobs you mention, most of those around here are in construction so they are seasonal. There are weeks/months at a time when it's too cold to pour concrete, lay bricks etc. The jobs in the extreme heat here would be seasonal as well, as really, there are only 2 months out of the year that its extremely hot.
Burnout in the workplace is generally NOT referred to just hours worked, the amount of hours you work can directly contribute to it but it's not the definition of it. I can see how that might make you view the situation a certain way if you are only thinking about it as in "meh 40 hours ain't nothin'"
Oh I know there are certain jobs, like I mentioned earlier, like in the medical field or prisons that can be very mentally draining. But again, I just don't think that 40 hrs a week is that much and if you can't deal with the mental strain of your job 40 hrs a week, it's not the job for you. The last year, even 40 hrs a week in a hospital could be very draining for sure.
But what about your job is so bad that 40 hours a week makes it too much that you'd get burned out enough that 8 hrs less a week would make a difference? I've had jobs I hated, where I was I supposed burned out from doing the repetitive work, but one less shift a week wouldn't have changed that. I moved on to a different job but the person who took that one thrives on the repetitiveness of it and loves it. I guess I just don't get it. If it's the work itself, or the environment (harassment, negativity etc) changing the definition of full time to 32 hours isn't going to make a difference in that. If it's the physical ability to do the job, I can understand that leading to burnout, but that's an issue for the employee to address that has nothing to do with 32 hrs vs 40. You either ask for accommodations or move on to something else. The employer has to make reasonable accommodations for you if it's a medical condition, but sometimes there isn't a reasonable accommodation to be made. None of these things changes with the change of a 32 hr work week. So other than hours worked, I don't see how anything that leads to burn out is going to be helped by this change. Which leads me back to 40 hours isn't that much and perhaps another job exists out there that you'd be happier with.
I absolutely understand there has to be a balance between profits and employee satisfaction, and that lots of businesses could and should do better. There are thousands of places out there who could do better for their staff. But there are also several just trying to stay afloat. Or who have a ton of revenue coming in, but barely any profit. But again thats something we (in general) don't take into account. We see that this business has 7 million a year in revenue but don't take into account what is left after paying everything, just see that revenue and say oh they can afford more.
