Hi Shannon! I send a weekly email with program updates, announcements, etc. Each email has the same subject line plus the date (example: SouthFit Notes, 7/20/11), so they get consistency. The email is also very brief, so it doesn’t take them long to read.
While each instructor is responsible for finding his/her own subs, if I need to find a sub I send a mass text to the instructors who teach that particular format. I can usually find a sub in less than 15-20 minutes.
Always looking for a more efficient way though. 🙂
