We had no remote teammates. Not sure how we would have handled that :-)

Some of the other offenses:

* Breaking the build (unit tests only) and then leaving for the day without fixing it or reverting your change

* Walking away without logging out of your machine (very security-conscious business)

* Not completing an assigned code review within a week of being assigned (within reason -- if the code review was enormous, or you were overly busy with an enormous project of your own, don't worry about it)
