Experienced worker troubled me on a jury, note (10)
I believe the answer is:
journeyman
'experienced worker' is the definition.
'journeyman' can be an answer for 'worker' (journeyman is a kind of worker). I am unsure of the 'experienced' bit.
'troubled me on a jury note' is the wordplay.
'troubled' indicates anagramming the letters.
'note' becomes 'n' (abbreviation).
'me'+'on'+'a'+'jury'='meonajury'
'meonajury' anagrammed gives 'journeyma'.
'journeyma'+'n'='JOURNEYMAN'
Can you help me to learn more?
(Other definitions for journeyman that I've seen before include "Competent, but not exceptional, worker" , "hired worker" , "Adequately competent worker" .)
