Sneaky little booger

I assume other schools are the same: at the beginning of the year you read the faculty handbook and sign that you have read it and are responsible for what is in it.

So that, later, when you have a question, the administrators can say "have you read the handbook?"

So what do you do when the administrators change what is in it (file date tells you SOOOO much, guys) but do not change the name of the file (which included a summer date) and do not let the teachers know there have been changes?

Wonder what is in there that they are going to make me responsible for? That I haven't read?
