I believe the answer is:
temp
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">short-term worker</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for temp that I've seen before include "Short-time worker" , "Non-full time employee" , "Short-term office worker" , "relief" , "Non-permanent worker" .)
