One of the factors to the prevalence of burnout, high turnover at minimum wage jobs and general reluctance of the younger generation to want to give '110%' to their job is...
That they're already doing that. Most jobs have a fairly limited parameter but a few economic crashes ago we started dissolving individual jobs like "Cashier, Host, Line Cook, Janitor", etc and start implementing jobs like "Team Member, Regular Crew, Manager (during this specific time period when the actual middle manager can't be around)", etc.
When this change first happened there were people with experience around who could take on other tasks because they were already good at their job and had a little time in between (time that is essential for good performance and health, but looks like waste to capitalists). But now we're having multiple generations thrown into the position of 'do literally anything needed in this building, do it quickly so the 'efficiency' timer doesn't get mad, and do it correctly so you don't get disciplined.
That's not normal. A normal work experience is not being wired 100% of the time and not being able to stop working except on the legally mandated breaks. But that is the baseline that is demanded.
It's untenable.
