Michelle, you make a great point and the best advice is to discuss these situations with your administration and fellow instructors. Be the agent of change and focus on what you can do to be part of the solution as opposed to being a continual part of a problem. This is similar to the discussion we as students at times, if someone else ran off a cliff would you follow? Of course we know in advance how we expect students to answer and this is the same for following the rules of an orderly classroom. You follow the rules because you respect your students and yourself, not because it is what others do or fail to do. Be that agent of change and bring the discussions forward within your professional group.
