IMO there are some really interesting CSB investigations into oil refinery/industrial accidents caused by bad software design (overwhelming operators with alarms is a big one.) Lots of people on here could gain by watching them. I used to put them on to fall asleep at night.
Oil is so much bigger than just refineries and oil wells. There's the upstream industry, the downstream industry, services and exploration, research, financial sectors, etc. etc. etc. There's a whole fleet of office workers to support them, and a lot of data to manage.
If we're thinking of the same YouTube channel, there are some excellent lessons to take away from those disaster investigations.
Now whenever I hear phrases like "we have to use the manual override most of the time" or "this alarm goes off all the time, it doesn't mean anything is broken", I am happy that the worst I can do is break a deployment, not explode an entire block.
I used to have an office job in the oil industry but the company I worked for had quite the opposite attitude. Due to a strong union there was a department where "restructured" people, to the tune of ~900 at some point - went on to do absolutely jack schitt until a project or activity needed resources. In which case you'd first have to go fish in that pond and if you simply couldn't find the correct skill set then you'd look for resources outside of the company. Some people stayed there for years until retirement.
On the field work side there were a couple of rounds of layoffs as automation started to kick in. Most in the field were contractors so their employer moved them around companies as needed. But for one person to see 30 rounds of layoffs I'd say it's still quite a bit of bad luck.
You might be surprised. Lots of people worked manual labour at some point.
But having been a roughneck after high school, no one higher than the rig manager would hold a speech in that industry. He'd get a call as we were finishing the hole and convey the news when everyone came in for lunch.
Possibly not directly, but two of my best friends were roughnecks, and then Deck Foreman. Unfortunately, one of them died just a few months back (not covid). Going to miss him down the pub.
