I believe the answer is:

strike gold

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

'place after industrial action' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'hit the jackpot in the first' is the wordplay.
I cannot really see how this works, but
'hit' could be 'strike' (synonyms) and 'strike' is located in the answer.
'first' could be 'gold' (I've seen this before) and 'gold' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
