i work in a data center right now. you are exactly right about the pros and cons. I used to work 6pm to 6am and I think that was even worse. I will eventually have the choice to move back to a 7am - 4pm schedule but its a hard decision to make because 2 day weekends are brutal after having 3 and 4 day ones. But I wouldnt miss out on stuff like the good DRs training race last night. I dread making the decision at this point.
