I am working for a private company & I need to spend 9-10 hours depending on the work I am assigned. Sometime I work during the weekends also.
As few as possible. I work in my home office all of the time. But, it is important to stay away from the work office. There are too many distractions and it is hard to get work done.
Actually I am working in a stock broking company so 6 an half hours have to work without wasting time.
