Ann, it might help you to determine what the official school policy is. You
may find that there is an unofficial policy that carries more pull. In that
case you have to decide whether you want to continue to fight the system.
At least by continually reminding him of your reasons for your objections
you remain assertive, while at the same time educating him. At the start of
each semester you can send him a memo asking to co-plan schedules. Record
and save all documents, yours, his replies, including no shows. Good luck!
Sincerely, Diane L.
