Worker returning woman's aerial (7)
I believe the answer is:
antenna
'aerial' is the definition.
('antenna' can be a synonym of 'aerial')
'worker returning woman's' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'returning' says the letters should be written in reverse.
'woman' becomes 'anne' (**).
'anne' backwards is 'enna'.
'ant'+'enna'='ANTENNA'
(Other definitions for antenna that I've seen before include "Aerial - insect feeler" , "Insect's feeler" , "Feeling part" , "receiver" , "one feels" .)
