If that's your definition of a "bad colleague" I would be a little concerned. There are situations where it may be necessary to do that struggle, but in my experience there are far fewer than you think, and people often fall into a trap of competing to be the last one standing rather than actually doing good work. If you're struggling in a data center at 2300 you may well be doing more harm than good and going home to sleep (or dance, or whatever you need to refresh yourself and come back focused...) is often a better choice.
