I'm starting to seriously resent the person I work with at night. I know he isn't a librarian by trade and he's not comfortable with every type of request. I also know I've offered to show him how to do other things and that he hasn't taken me up on it. So it means that for 5 hours every night I do 90% or more of the work. I've also made a habit of checking the next day when I come in to see if anything bounced back or if someone answered a question I wouldn't know how to do so I can learn.
I also see the numbers of what I did vs. him and sigh resignedly. I know it won't change. But what it does mean is that I'm leaving more at night undone since I'm not going to kill myself like I did at LIB where I felt like Sisyphus on the regular. I noticed that at 10 he signs off like clockwork. I run over by 15 minutes or so now if I'm in the middle of something or a quick follow-up comes in, but no more working until midnight. It seems that not doing 100% ALL THE TIME is accepted at SIB so I'm adopting it.
My 90% is still more than most, and I'm ok with that.
