Retired teacher Nancy Flanagan—now a doctoral candidate in education policy—thought it would be nice to go back to her old school as a substitute. Easier said than done:
I calculated that it would take three days of subbing to cover the registration fee alone—not counting the unpaid day of substitute training by a real live former teacher, the fingerprinting fee (and the pleasure of spending a morning at the county jail to accomplish that), the original certificate replacement costs, and the darned TB test. It would be October before I broke even.
