I worked in construction/manufacturing as labor, then in a CNC engineering capacity, then as middle management, then at a vendor for manufacturing as a software engineer.
All were progressively less work, but my god consumer tech isn’t even close. The people working the hardest seem to be the most keen on useless bureaucracy and bridges to nowhere somehow.
I’ll never go near it again. I also don’t think I’ll ever not be adjacent to manufacturing & construction again. “Tech” people are insane.
