I am not on the front lines of the microaggression circuit, but one thing that I think we should stop saying as educators to fellow peers is how young one looks. I am starting my 15th season of teaching and have been told: "I don't look old enough..." or "you look too young to..." EVERY SCHOOL YEAR. I am sure this is meant to be harmless...but does it? It is to say "you do not have my experience," "you are not a seasoned professional," or "you have much more to learn."
I have done this work for 15 years, constantly reading, updating my pedagogy, trying to fight back being jaded and burnt out, sending myself to expensive professional development training and making this work a part of who I am. In the 15 years, I have been an educator I have been naive in the eyes of my peers, and one who wears rose-colored glasses, or overly optimistic. I have worked hard for this youthful spirit, and keep working toward educating every student to the best of my ability every single day. I want to believe there is good in this world and in every student.
So please, let's keep wonderful educators in this wonderful field by not pushing them out because of your assumptions. Hold back, don't compare yourself to others. And if you think someone looks too young for something, ask them what face cream they use, and don't demean them for looking "too young." Because if they got the job, they are not too young...they are professionals, treat them that way.
