Do tenured faculty get to micromanage clinical professors and other non-tenured instructors with respect to the classroom?
It's is very common for certain core multi-section classes to be coordinated or standardized in some way.  For example, the textbook and sections covered are fixed, or there is a single final exam for all sections.  Such arrangements apply to all instructors in that class, no matter what their title.  Often there is a "course coordinator" who has some of the responsibility of enacting these department policies.  It is not unusual for the coordinator to be tenure-stream research faculty and the other instructors not to be, but it's also not unusual for experienced lecturers or clinical professors to coordinate.  (It would be quite unusual for a postdoc or other less experienced person to coordinate.). The level of micromanaging varies by course and department, but usually applies equally to all instructors regardless of title.
