Imagine if your boss came to you and said that you only need to be at work from 8:30 - 2:30 the rest of the hours you can work at home whenever you want. I think everyone here would jump at that offer. It gives you a tremendous amount of flexibility, you do the work when you want and you can make time for other activities. For example, I need to be in the office 9+ hours a day, and therefore when I get home many days my kids are asleep. If I could come home at 3PM, many days I would eat supper with my kids do things with them etc., and then after they go to sleep go back and do work. It is a tremendous thing to be able to decide that tonight you are going to work from 9PM - 11PM instead of having to be in the office from 3-5. In fact, I know teachers who take tests/papers with them when they go for a doctors/dentists appointment, and in the time that they are waiting they mark tests. I can't do that, my job is in the office.
