I just lived in Taiwan for about a year, and it's pretty common feeling there that TSMC is struggling "to get Americans to work hard" in Arizona. I had several folks mention it to me when TSMC came up as a topic. They're worried they'll have to start sending full teams of Taiwanese engineers over to staff the factory (in addition to those required for training & supervision).

That doesn't mean it's necessarily true -- folks in any country, in aggregate, tend to talk about themselves as harder working than their neighbors. But I think this general idea/complaint is way more prevalent than a few Glassdoor comments, even if that's where they sourced the article.

I don't know anything about semiconductors or manufacturing in general, but I do know a friend at TSMC had to buy a second apartment to sleep in because he works such long hours and didn't want the additional commute back to Taipei at night. It's also worth mentioning that -- like the SF and NYC set who maintain "work" apartments -- this guy is compensated very, very well.
