Workers group has time doubled - disgraceful (3-3)
I believe the answer is:
tut-tut
'workers group has time doubled disgraceful' is the definition.
I can't judge whether this defines the answer.
'workers group has time doubled' is the wordplay.
'workers' becomes 'tu' (abbreviation for trade union).
'group has time' becomes 't' (I can't explain this - if you can you should believe this answer much more).
'doubled' says to double the letters.
'tu'+'t'='tut'
'tut' duplicated is 'TUT-TUT'.
Can you help me to learn more?
(Other definitions for tut-tut that I've seen before include "For shame!" , "Repetitive expression of disapproval or rebuke" , "Mild exclamation of disapproval" , "Repetitive exclamation of disapproval or annoyance" , "Expression of disapproval, contempt" .)
