Try job that involves most of all woodwork (8)
I believe the answer is:
goalpost
'woodwork' is the definition.
(I've seen this before)
'try job that involves most of all' is the wordplay.
'try' becomes 'go' (both can mean an attempt).
'job' becomes 'post' (post is a kind of job).
'that involves' indicates putting letters inside.
'most of' means to remove the last letter.
'go'+'post'='gopost'
'all' with its last letter taken off is 'al'.
'gopost' going around 'al' is 'GOALPOST'.
(Other definitions for goalpost that I've seen before include "one unfairly moved" , "Upright with net attached" , "One of four supporters at ends of pitch" , "woodwork" , "it's unfair to move" .)
