Sorry, this ended up a little long lol. Sign of my age I guess...
I was an IBEW Local 11 inside wireman back in the mid ’80s through the mid-’90s (did my apprenticeship through the union). Worked for AV Jensen Elec, Comet, DGS, and Security Elec... Berg briefly. I worked on Back to the Future the Ride at Universal, Calif Tower 2, Warner offices in Burbank, Hues Helicopter in El Segundo (remember them filming a scene for Judge Dredd when I was there) and various Lockheed and other aerospace buildings. I was doing earthquake repairs at the capitol when the OJ trial was going on... still have pictures from up on the scaffolding around the dome looking down on all the news vans
I moved to Denmark

in 96' and joined the local union there, DEF (Dansk El Forbund), ironically, also Local 11 out of Aarhus. I ended up transitioning into electrical manufacturing, building panels and wiring production line equipment for the ice cream industry. Our main U.S. customers were Ben & Jerry’s, Unilever, and Nestlé. No idea how things are going now... I’m guessing our already very pricey Danish produced equipment is even more expensive now (tariffs).
It was interesting work, and my colleagues were all very skilled electricians, machinist, and mechanics (engineers and programers)... all stainless steel so a relatively clean work/factory. I learned a great deal from them. We were also a tight nit group (I still keep in touch). The electricians club made outings to our local Aarhus "fest" week every summer, and we arranged trips to visit various work related companies (about one trip a year). Standouts were Danfoss who manufactures frequency converter/drives, NKT cable and wire manufacturer, Henning Olsen Ice Cream in Norway, Workers Museum in Copenhagen... and of course Carlsberg also in Copenhagen (to see their production line of course). These were often weekend trips funded by a combination of the union, HR and our own El club at work. Grundfoss was a day trip... only 10 minutes from my home.
I was sent to Milan in 06' for a month (august) with a coworker to help finish up some freezers for our sister company there... other than that I wasn't a field installer... but I did get to go to a "Lidl" plant (they are a large grocery chain, similar to Aldi) in Aachen Germany a few weekends to help adjust and change some cabling on a couple large lines we installed there not long before I moved back.
I stayed with that company for 22 years before moving back to the States

. Since then, I’ve been working as maintenance l/coordinator at a large high school and am a member of CSEA. I didn’t want to go back to installation work after being away from it for so long — and at 53, it just didn’t make sense to start over in that line of work again.
I did apply for some positions I thought would be a good fit at Northrop, Lockheed, and Vestas (their windmills are built near where I lived in Denmark, and they use similar drawings and wiring methods). It took Northrop almost two years to get back to me to say I’d made it to the next step, but by that point I was already settled into my job with the school district, so I stayed put.
I’m really happy where I’m at, especially after making such a big move later in life. The hours are great, I’m five minutes from home, the benefits and vacation are solid, and the pay’s decent... I don't make as much as a union electrician of course but the tradeoffs are worth it... especially working the same location every day... NO commute... Even in DK, though I worked in a (nice heated) factory the entire time, I had a 75 min commute each way as we had a home and property in the country (it was worth it).
Losing universal health care was honestly the scariest part about moving back to the U.S, and I used to get six weeks of vacation a year (plus holidays), which was great when the kids were growing up, but now that I’m on my own and an empty nester, I’m fine with what amounts to half that plus I have a decent amount of sick time built up over the last six years.
I have always benefited from being a union member (life long since I was 19), in the three unions I have been a part of. The dues have been negligible compared to the benefits I've received.
