On 996: it is way less common than people seems to think. It was a fringe practice in ~40 companies during the tech boom. It has since been made illegal and is declining from it’s already fringe position.
While overtime pressure which was more common and 996 still does unfortunately exist, the trend is clearly negative. As in, it’s being actively cracked down on. The Supreme Court ruled 996 illegal in 2021, and recent policy pushes like the 2025 Consumption Boost Plan are specifically targeting illegal overtime and pushing for better enforcement of rest/vacation rights among other benefits. It’s not perfect, obviously, but it’s hugely improved from where things were in the 2000s or even 2010s, and honestly it’s just not the omnipresent norm that English-language coverage sometimes makes it sound like.
