<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">personnel</span>' is the definition.<br/ ><span class="explanation-format__explanation">(staff is a kind of personnel)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for staff that I've seen before include "Group of employees and long stick for support" , "team?" , "the general's assistants recognised" , "Post - office workers" , "Rod of authority" .)
