That would be considered illegal here, is it legal where Greptile is based or are they breaking laws? I'm not saying this makes the practice any better, but I want to know if this actually puts them at risk of punishment.
I think it’s certain hourly-wage jobs that have can hour limits. (ie. physically demanding jobs in hot weather conditions require periodic water breaks, in addition to hour limits)
In other hourly-wage jobs, you can still work over 40 hours but the worker is entitled to over-time pay. My mom worked at the US Post Office and during the holiday seasons she would sometimes work 12 hours a days, but all hours above 8 were paid at twice the hourly rate. Also, note that signing up for overtime was voluntary.
Software engineers, on the other hand, are salaried. Similar to lawyers, they sometimes have grueling hours (ie sleep in the office) but it’s not illegal, afaik.
