If you are feeling ill at all and feel you may need the next day off, it is best to contact a few people the evening before to see who is available and keep them on standby for the next morning. That way, a quick text in the morning will resolve everything, either way.
Once a replacement has been found, send an email or text to me with information about the switch. If a Lesson Plan is possible, all the better.
This does not apply for Holiday Requests. I can still take care of those given I have ample time to organize (and vet the teacher should it be for a longer period of time).
If there are any questions, you know where to find me.
