Together as public service union members? (2,6)
I believe the answer is:
in unison
'together' is the definition.
(I've seen this in another clue)
'as public service union members?' is the wordplay.
I cannot quite see how this works, but
'as' could be 'so' (I've seen this in other clues) and 'so' is found within the answer.
'union' could be 'u' (common abbreviation as in 'Trades Union Congress') and 'u' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for in unison that I've seen before include "All speaking or singing at the same time" , "All singing the same notes" , "All speaking or singing as one" , "Simultaneously" , "All together at the same pitch" .)
