If you need a sub

If you need a substitute, here are some do's and don't's from my perspective, the perspective of a sub:
1) Leave a class list and an accurate seating chart. I can't say how many times I don't even know who or how many students to expect. Seating charts are out-dated 9 times out of 10 once the second semester rolls around. What if there's an emergency and I can't tell the administration who was in my/your class?
2) If you expect excellent or lazy behavior from your students, that is fine, just let me know. If you let your students run around all crazy, you've made my job 5 times harder, especially if you don't tell me that's the norm.
3) Leave me lesson plan options. Don't assume that I know everything or nothing about your subject or technology. Leave options, so if I feel comfortable going over your material, I can. If I know nothing about it, leave me something simple like book-work or a movie as a second option.
4) ALWAYS leave me something to do! Over-plan if necessary! Having nothing to do is a painful experience as a sub. Imagine how your students behave for you on their worst day, and now multiply it to see how they treat a sub. Give us something to accomplish or there is mayhem!
5) Leave things where we can find them and leave the teacher's computer logged on for us. Imagine moving into a fully furnished house and being told to find the garlic press. You may have an idea of where to look, but the owner may have thought a different place was logical. Leaving a working computer for us is just courteous. It is like leaving the remote control out so a guest can watch TV during downtime. We need the downtime just as much as you do.
6) Say thank you. You know who subs for you. We leave feedback on papers in your room and online. If you think your job as a teacher is thankless, try being a sub. We work hard at half the pay and no benefits. It would go a long way. It isn't easy walking into someone else's room, dealing with someone else's organization, and trying to make it all work.

Thanks, and thanks to all the teachers who do as much of this as possible!
