I think that one reason listening is difficult in the school environment is the fact that we have so little time to do all our work and collaborate too.
We pack so much into short meetings and our little bits of time to collaborate that I always feel rushed since I know time is short, the decisions are important, and there's multiple other items to plan, prepare for, and create with regard to the teaching ahead.
Also because, as a planner, I can see the many tasks related to a project from beginning to end, I know how important those meetings are with regard to a project's success.
Yet, that's no excuse for not listening or not listening well as we know it's a critical skill when it comes to working well with and for others.
