TO MIDDLE SCHOOL & HIGH SCHOOL TEACHERS:
If you want me to substitute teach for you, please send me an email at email@example.com or call me at 202 230 4776. You can also just put the job in SEMS. If SEMS says I am not available let me know and I will cancel any system generated jobs to take care of you. I much more prefer to return to classes where the teacher has invited me. (Although a new experience is always FUN).
