The American Federation of Teachers has released a report (here) complete with an interactive excel tool designed to both motivate colleges to convert more adjuncts to full-time status and to pay adjuncts on a pro-rata basis. The spreadsheet allows you, in theory, to plug in the numbers from your own college to see what it would cost to hit a targeted full-time/adjunct ratio. It's a surreal read. Check it out. It shouldn't take more than a few minutes.
