Why electrician? My father is a licensed (but not union) electrician and I used to work as his assistant when I was a teenager. The job was pretty boring, mostly driving to job sites, running cables, wiring them up, etc. It never struck me as an intellectually stimulating job. He had a book with a bunch of formulas in it (called Ugly's, iirc) that I would read while driving to sites sometimes, but it was plug-and-chug algebra.
I wouldn't want to be an on-call electrician, driving out and fixing ovens and light switches. Most of my tradie mates try to avoid those kinds of jobs too, ideally a job doing fit out on a large commercial worksite is what you want, office buildings and that kind of thing, even better if it's a union worksite.
I've always enjoyed construction work though (electrical and other), sure it's not intellectually stimulating, but it's rewarding. Sometimes I actually regret having such an intellectually demanding day job, after 8 hours of work often I'm too mentally drained to do what I want in the evening. There's also a certain sense of satisfaction from seeing your physical finished work that you just don't get as a software developer.
Working as an industrial electrician would be more my kind of thing, performing maintenance on machinery, programming PLCs, that kind of thing. Repairing equipment requires a lot of the same mental processes as debugging code, I enjoy doing both. It's a good cross between physical and mental work. The money is very reasonable, up to $50 an hour.
