Recently, the flu felled 18 of our teachers at once, including 3 from our science department. That's three subs with NO sub plans! Now that the chaos has settled, we've compiled a single folder of emergency sub 'locator notes' for the whole department. It notes the locations of such things as roll sheets, seating charts, VCR and TV remotes, cabinet keys, gas and water shut off valves and how to use them, etc. We keep these 'locator notes' for each teacher in our department prep room for easy access.
