Ohmigawd! Ever since I was hired part-time as reference support staff in 1995, I have worked a Tuesday-Saturday schedule. This is my inaugural weekend as a M-F person. Of course, I'll be on a weekend rotation (every 3rd Saturday, every 6th weekend), but this is my first Friday to be home, chill out and know that I don't have to be up at any time I don't want to be up Saturday morning.
When I got my MSLIS degree in '98 and became a full-time, (capital L) Librarian, I was given the chance to adopt a M-F schedule. At that time I had younger kids--they had a lot of school holidays on Mondays, and they were with their papa on Saturdays, so it made sense to keep my Tue-Sat schedule. As they are older (10 and 13) and don't need (or want!) me as much, and have more Saturday activities, a good ol' Amerkian M-F schedule makes more sense (yeah, I still have one night per week, so it's not strictly a 9-5 deal).
Do you have any idea how long it's been since I've been to a garage sale?
