I mean the regular teachers have another time table for substitution. Three periods per week for each one. In my district there is no training for subs. Not even a handbook. You just get thrown in the first time.
Some teachers leave no plans.
I have even subbed for a few who won't allow you to use their plans. At least we get attendance sheets, sometimes thats the only class list you have. I mean substitute teachers get full salaries. They are supposed to be updated each year and initialed by the principal. They contain info such as fire drill info, daily schedule, class list, dittos, etc.
