First of all, any issues that are related to a teacher and the secretary are none of your business really. Whatever happened between them is their issue - and you getting involved is completely unnecessary. If you feel that she has an attitude problem - then thats something completely separate and its something that you'd have to take up with her.

As far as the biochem professor goes - thats your opinion. If other students felt another way - well thats their opinion as well. The teacher is gone and you'll have to move on. If you believe that we ignore the real issues - then tell us what the real issues are?
