Pros
They've got incredibly funding and the schools are beautiful. It is a safe environment for children to learn in. The school gives opportunity to children who wouldn't have access to a great school and they do learn the content and perform well on tests.
Cons
I felt completely taken advantage of as a teacher. Way overworked (even relative to a prior career that was extremely demanding), felt very little respect from network. Didn't care about my work-life balance, personal health, emotional well-being. Was assigned way more tasks than what I believe a teacher should be asked to do (which resulted in lower quality work in the classroom). Extremely micromanaged, which was forced upon me in my work, and forced upon students as well. Little creativity encouraged in learning.
