You wont work less hours here no matter what business you are in. The average working week is longer in the US. Some people in jobs work 50 hours plus. I know a nurse who works 70. My cleaners work 9-5 in a day job and then 6-10 pm cleaning offices and one even cleans Saturday morning. The norm is no paid holiday or very little paid holiday
so most people take 10 days off or even less. No statutory four weeks here. In your own business, if you dont put the hours in to stay competetive, you wont survive. Some people here work 24/7. There is no safety net if you fail here, no unmeployment benefit or social security for us and if we fail we lose the right to remain in the US. So we all feel the fear.
