Time Magazine has come out with its America by the Numbers 2007 report. Part of the report includes a poll on job satisfaction. I've seen librarian polls on job satisfaction before--we've always rated our satisfaction poorly. So, I wasn't surprised to see that only 25.2% of the librarians polled said that they are "very happy."
I would like to just say that I'm in that 25.2%.
