|World War I Trenches|
I think that the language of war emphasizes zero sum game thinking and increases teacher loneliness. It sets up a feeling of us vs. them. The war metaphor leads to negativity. This sense of war may very well contribute to teachers dropping out. If you define education as combat eventually the soldiers get tired they want to go home. We might lead a brilliant charge and Teach Like their Hair's on Fire, but that cannot last for a full career.
We need better metaphors. Ones that admit the challenges and obstacles but also admits the positive, the possibility of collaboration. Metaphors are powerful in orienting our dispositions and choosing the right ones can change the way we see the world.
