I think that is a somewhat cynical view of the matter; I appreciate that "American Work Ethics" are highly flawed and mostly theatrics (I say this as an American expat who has experienced work from all over the globe), but as much as there is management theatrics in the US, there's also a lot of "woe is me" from employees when they're disciplined.

I'd really hate to see how the author of the piece would have reacted to the Russian Managers at the company I'm with at the moment, as the managers certainly don't sugar coat when they're unhappy; it's not abusive, it's just very to the point. Having been a manager when I still worked in the US, it was incredibly difficult to correct inappropriate behavior because virtually every time you did, you did it wrong to whoever you were correcting. Try to be gentle? You were unclear. Try to be polite but to the point? You were curt. This sort of dance suggests to me that we just don't handle criticism well professionally in the US. I'm sure this is just observer bias, but I see a tendency to avoid confrontation at any cost, with too many places hoping it just "works out".

I do think it's from both sides of the employer/employee line. I have been at places that were more interested in just removing people who had some bad habits or needed to have a line drawn for some behavior while otherwise being model employees. I have also seen employees who were absolutely resistant to any criticism for a multitude of reasons, and ultimately the just continued with bad behavior until they were fired or left the company out of frustration with the constant meetings.

The author touches on some very true feelings in the article - no one likes being reprimanded. It's harsh, it's embarrassing, and it saps your ego for many reasons. But like others have commented, I do think that they acted unprofessionally - I imagine the story would have been much different had the author simply PM's a manager or boss "hey, family issue, going to be incognito today, I'll try to get an update by X" or just anything to keep them in the loop. The author also seemed unaware of the expectations of their bosses before hand, so maybe that's the fault of the company or the fault of the author. The age disparity I appreciate the uncomfortableness of, but it's going to be something that is more and more of a reality. (Ageism in tech is very real, so not discounting that, but the reality of the world is that there are going to be many young tech managers; staying out of management is great, but it needs to come with the understanding that eventually you'll be older than your bosses on average).
