Bothersome judicial work (6)
I believe the answer is:
trying
'bothersome' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for trying that I've seen before include "Aggravating" , "undertaking" , "Difficult - hearing" , "Exasperating" , "Attempting or stretching patience to the limit" .)
