Recently [back in February 2009], a group of 'contingent' faculty began the process of developing a national organization for 'contingent' [auxiliary, adjunct, other] faculty. Their current website can be viewed at
http://www.newfacultymajority.org. Interested individuals can participate in the organizing committee, research committee, and/or simply sign-up to receive further notices by e-mail as the group develops. Go to the website for further information about their interests, their advocacy, and their plans...
I say, about time!
