i do bare minimum office work. Just like paying taxes i do just enough that i don't get called up. Every manager has a time schedule. Most Indian managers think we work hard if we send out lot of emails, and work late. American managers are happy as long as they do not get any escalations. EU guys are quite flexible if you tell them the truth and be open about work life balance.
So my wife and myself have managed schedules accordingly. Both of us has understood the value of Joint family set up. So to nothing to worry for now. The only problem is youtube. As long as thats in control, we should be safe.
