<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">it's not working</span>' is the definition.<br/ ><span class="explanation-format__explanation">(leisure time)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for leisure that I've seen before include "Convenient opportunity" , "retirement" , "time-off" , "Time when not working" , "Ease; time off work" .)
