I get the feeling that a lot of discontent related to the archaic 8-hour work day. I have personally interacted with at least a dozen other engineers at my workplace who openly admit they "actually" work maybe 2 hours a day. The rest of the day is spent idly feeling burned out forced to sit at their workstation for the next meeting or instant message to reply to. I personally suffer burnout from this.
