I'm trying to remember if there is any scene in which Crusher addresses Troi in any way that would identify her as a subordinate in her department. None come to mind.
I always pictured Troi as having a busy schedule while providing psychiatric sessions to the crew as well as having a substantial role in helping Picard do his "homework" prior to any diplomatic engagment.
I don't remember Troi ever calling Crusher or Riker by "Sir".
