Tigerish blow to industrial peace? (7,6)
I believe the answer is:
wildcat strike
'industrial peace?' is the definition.
The definition suggests a singular noun which matches the answer.
'tigerish blow' is the wordplay.
'tigerish' becomes 'wildcat' (I can't explain this - if you can you should give a lot more credence to this answer).
'blow' becomes 'strike' (strike is a kind of blow).
'wildcat'+'strike'='WILDCAT STRIKE'
'to' is the link.
Can you help me to learn more?
(Other definitions for wildcat strike that I've seen before include "sudden action" , "Unofficial walkout" , "Unofficial downing of tools" , "Industrial action" , "unexpected disruption" .)
