Why would say medical report to security daily?
Say Ensign Ricky's got a hangnail or Crewman Erik a sore throat. Does Tuvok need to know that? Daily or at all?
Why would Security need to know whats happening in Engineering either or whatever department Paris is in charge of. It seems ridiculous to me unless Tuvok needs some make work?
I think he needed to be keeping a better eye on the Marquis or on supplies or potential Delta quadrant threats or something but I don't any department heads would need to report to him daily weekly or monthly.
