Song social worker's embarrassed about (6)
I believe the answer is:
shanty
'song' is the definition.
(shanty is a kind of song)
'social worker's embarrassed about' is the wordplay.
'social worker' becomes 'ant' (I've seen this before).
'embarrassed' becomes 'shy' (I am not sure about this - if you are sure you should believe this answer much more).
'about' is an insertion indicator.
'ant' put inside 'shy' is 'SHANTY'.
Can you help me to learn more?
(Other definitions for shanty that I've seen before include "sea air" , "Seafaring song" , "Sailor's work song - ramshackle hut" , "A song for sailors or a ramshackle house" , "Poor home - sailors' song" .)
