I live in western europe and the usual office time is 9:00 - 18:00, with 1h break. I've heard so many times that in the US people work 9-5 but the math doesn't adds up: do people in US work less than 40h (8x5days) a week? Is there a paid lunch-break? I read This related question but didn't quite understand what's the nowadays standard.
Do people in US work less than 40h (8x5days) a week? Is there a paid lunch-break?
Some do. Some don't.
Everywhere I have ever worked had unpaid lunch breaks. Usually that meant working 8:00 - 17:00 or the equivalent or more.
Most salaried people I have worked with, work more than 40 hours per week.
