I am currently a graduate TA and my duties include preparing tutorials for an undergrad course, we are supposed to prepare the sessions based on the material sent to us by the professor.
The problem is that the professor has been emailing the material 1 hour before my tutorial starts for three weeks in a row. I feel like I can't prepare anything decent in such little time. Last week I asked the professor to please send the material with more time, the professor agreed but this week she did the same thing anyway. When I saw that 2 hours before the tutorial started I had no news from the Prof, I prepared the material myself and ignored her email that was sent 1 hour before my tutorial.
I definitely have to write something to her since the instructor should know what happens in the tutorial sessions, but what do I tell her? It might sound aggressive to say "if you don't send me the material with enough time I will just do whatever I want", but that is exactly what I want to say (in a different tone). Am I wrong here? If you are a prof, how would you react to something like that?
