The company is not and must never claim to be home, family, religion, life or fate for the individual. It must never interfere in his private life or his citizenship. He is tied to the company through a voluntary and cancellable employment contract, not through some mystical or indissoluble bond.
Everything in life requires that you make trade-offs. If you believe that your work comes after your personal life, you are trading off the results you need to provide the best life possible for you and the people you care about. If you believe that your personal life comes after work, you will neglect the most important people in your life.
Making yourself available to your work 24/7 exposes you to a constant barrage of stressors that prevent you from refocusing and recharging.
