I'm a little stuck... Click here to teach me more about this clue!

'day ran short during strike' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'final action' is the wordplay.
'final' becomes 'last' (synonyms).
'action' becomes 'hurrah' (I am not sure about this - if you are sure you should believe this answer much more).
'last'+'hurrah'='LAST HURRAH'

'for' acts as a link.

Can you help me to learn more?

(Another definition for last hurrah that I've seen is " Final performance".)

I've seen this clue in The Times.
