If you don’t want to work more than 40 hrs a week. Don’t. Afraid of company retaliation? Find another job at a company where the culture is more in line with your views. Better yet, start your own company and work as little as you want.
Life work balance is on you. Regardless of who you work for or with in the US.
If you still want to whine about it, join the armed forces, serve your country, and get back to us about work ethic and life balance. I’ll wait.
