Probably something in medicine although people are occasionally crazy and that would violate your #3

Shepard. Physical therapist.

Not quite the answer you’re looking for, but I’ll shoot. Die setter with a plastic injection company. It can be stressful with our schedule, it’s physically taxing (sorry knees, sorry back), and it’s dirty as hell (you never quite wash the grease and oil off your arms)…BUT it’s fun in a way, you have to be mentally present, it’s a great workout (I’ve never been in better shape) and it’s interesting. Not saying you should move to the Midwest to make plastic car parts, but manual labor can be really enjoyable in the right circumstances. Plus you can play with tools which are essentially toys with the right mindset (“oh boy I can run to the hardware store for a new ratchet! I can’t wait to work with it!”). Just my two cents.

I’m a software dev. Checks off the 3 bullet points you listed but the 9-5 grind has slowly been getting to me lately. If I wasn’t already planning to quit soon to work on my own projects (and maybe start a worker coop), it probably wouldn’t be too hard to find something more chill and with less hours in the public sector or find some company working on something I actually care about.

In the US the public sector has decent consistent hours and good benefits. Maybe you could work for the labor department equivalent for NZ? What type of law are you working in?
