They try to do their jobs (6)
I believe the answer is:
judges
'they try' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for judges that I've seen before include "Decides (results of competition)" , "Gives verdict on; book" , "They decide the winners" , "Hears, Bible book" , "They try" .)
