Don’t do that then. Work on 90% with bursts of 130%. Don’t work on 120% all the time because it’ll be assumed you’ve gotten lazy when you just need to slow down.
In U.S. even though a full-time job is “40 hours”, many in non-government jobs put in more. The “120%” spoken of would be 48, so let’s say roughly 2 extra hours a day, so 7:30-18:30 with an hour lunch. Tech startups in my experience are usually 44-46 hours for low-mid IC dev or more if higher or any lead/manager responsibilities. Some dev/IT managers may be on-call most of the week. But some people literally are working 40 hours/week.
Other countries “100%” hours/week are roughly:
Europe 35-40,
Eastern Europe ~40,
India 45-55,
China 45-50,
Africa 40-50.
And similar applies for dev/IT startups and management.
Some work > 100 hours week on average, but I think that’s difficult to do in dev/IT for more than a month at a time without burnout, even if you just keep hitting a button over and over.
If a country expects 40+ hours on average then they should also expect an inverted demographic pyramid within a generation or two. Many such cases. It's a great way to commit national seppuku.
