Report of panic -- workers finally revolt (9)
I believe the answer is:
statement
'report' is the definition.
(I've seen this in another clue)
'panic workers finally revolt' is the wordplay.
'panic' becomes 'state' (I've seen this in other clues).
'workers' becomes 'men' (men can mean staff or employees).
'finally' says to take the final letters.
The final letter of 'revolt' is 't'.
'state'+'men'+'t'='STATEMENT'
'of' acts as a link.
(Other definitions for statement that I've seen before include "Bank account document" , "may be taken by police" , "Declaration of facts" , "Proclamation" , "Formal account of events" .)
