I admit that I under-dress for class. That being said, I teach a technical certification course where the students are predominately young adults dressed in jeans, tee shirts, and flip-flops. As I dressed professionally the first few weeks, a line quickly appeared. This line was clearly erased around the third week, when I started to dress as they did. My point is that, as in life, every situation is different. By my breaking protocol, the students better related to me; yet, in my opinion, I was still able to be a successful model, manager and motivator.
Does this indeed show a lack of professionalism, as this module would have you believe?
