I have found that when work is required after hours, the "1040ez" crowd are the first to "whine" about their precious time being taken away.The majority of them were hourly and still "b1tched" about it. Mature IT workers resolve issues, young IT workers apply "band-aids and work-arounds. I have had employess of all ages and each age group has it's share of weak IT skills. I also have found that veterans, young and old, have all of traits you've listed.
