Many new principals have been trained in quickie programs of a year or less, which try to teach them to think like corporate leaders. Many of the graduates of these new principal programs have little classroom experience, and some have none at all. Many of them lack the judgment and knowledge to make wise decisions about curriculum and instruction or to evaluate seasoned teachers.
When experienced teachers must work under the control of an inexperienced principal, they need the protection of their union against arbitrary and unwise decisions.
