One feels social worker, Anne, should be retired (7)
I believe the answer is:
antenna
'one feels' is the definition.
(an antenna feels things)
'social worker anne should be retired' is the wordplay.
'social worker' becomes 'ant' (ants are social insects).
'should be retired' says the letters should be written backwards (retire can mean to go back).
'anne' in reverse letter order is 'enna'.
'ant'+'enna'='ANTENNA'
(Other definitions for antenna that I've seen before include "sensitive feeler" , "Insect's feeler" , "could send out a message" , "one feels" , "Transmitting aerial" .)
