I teach in Missouri. I don’t think the state makes a difference. As you’re finding, every district operates differently, regardless of the state it is in. All I can tell you is meetings during plan time and after-school commitments only make sense. Although not always, they are often necessary and worthwhile. They lead to professional growth and student growth. There is a reason this district you are considering is highly sought after and people don’t leave, despite the fact that they are expected to to attend meetings and join committees. They must believe in what they are doing, and they must feel that they are getting something out of it. Otherwise, they wouldn’t stay. Only you can know what is right for you with this opportunity or any other. But I caution you to avoid turning down a job simply because it seems like more work or more of a time commitment than you have currently, especially so early in your career. Putting in the time now will propel you forward in the future.
