Is the 2 hours lunch/break time sacrosanct? Meaning, pretty much everyone does it? I rarely take a long break during the working day, lunch is 30min at most. But, I like to leave a bit earlier to spend time with my daughter. Once she's in bed at night, I'll usually work for a few more hours though. So, I may not be a good example.
