Would You Prefer To Have Expectations Clearly Spelled Out By Your Superiors?

Yes. That way everyone is on the same page.

Yes I would expect no less. If they are any kind of Boss or Manager, they should lay down the ground rules and then stick by them. That way everyone knows what's expected of them.

Of course. As in any relationship, whether it be friends, teacher/student, employer/employee or superior/worker communication is key. Not only should the superior explain everything clearly and concisely, the other person should also ask a question if they don't understand.
