People who do this are useless. They burn out and can't do their regular jobs, and boring people with no life aren't useful in any sort of position that requires you to think because they've never had the time or bandwidth to learn how.

Source: started going down this road, realized it was counterproductive, and now avoid hiring people like this.

Most places I've worked, people would just wonder why you were so inefficient that you needed the extra time to do your job. Like, yeah everyone else does this shit in 40 hours, but this guy keeps showing up on Saturday, so he's either fucking around during the week or he's bad at his job. Anywhere that would think it was a good thing wasn't the kind of place you wanted to move up, it was the kind you tried to leave as soon as you could. Because they were run by the kind of morons who think the appearance of working harder was more valuable than actually doing something useful.

Early in my career, I picked up as much overtime as I could at the hospital. I worked 13 days in a row with three of the those days being 12 hour shifts. My coworkers informed that I was a real bitch after day 7 and it would be better for all of us if I didn't work more than seven days in a row.

I took their words to heart. There's working hard to get ahead and then there is killing yourself and making everyone around you miserable.

Well with the wealth gap inequity and the notion of meritocracy having been proven a farce for the past couple generations…. This advice is utter bullshit.

I would say that for someone who is willing to work multiple full time jobs and choose to “live to work” they could potentially save up enough money to send back to help their family in a second or third world country.
