Account reconciliations for month-end
Tracking office supplies
Posting job ads
Coordinating monthly onsite paper shredding
Updating departmental metric spreadsheets
I could go on forever. Funny thing is in pretty much every instance, when I finally did delegate something, the person I delegated it to would say "it's about time" or "I was wondering when you were going to do that". I finally added a question to all of my quarterly conversations asking if there was anything I was doing that they felt they could or should be doing. Needless to say the results were amazing.
