A lot of people do think of subbing as a profession. I know several people that sub for a living, and I believe there are even a few posters on this forum that plan on subbing for the long-term. And I'll have to disagree with you on the second point. If they offered more money for subbing, there would be a lot more people attracted to subbing. That would mean more competition, which would mean teachers would be able to choose which subs they like. Right now, in my district, they take what they can get. I also thought I'd mention that in my district people don't need a teaching certification to be a substitute teacher. You just need 62 college credits with 6 in teaching, or a bachelor's and the 6 teaching credits are waived.
