Ganger to accuse the labourer (10)

I believe the answer is:

chargehand

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

'ganger' is the definition.
I know nothing about this answer so I can't judge whether this works.

'accuse the labourer' is the wordplay.
'accuse' becomes 'charge' (charging is a kind of accusing).
'the labourer' becomes 'hand' (hand is a kind of labourer).
'charge'+'hand'='CHARGEHAND'

'to' acts as a link.

Can you help me to learn more?

(Another definition for chargehand that I've seen is " Supervisor".)

I've seen this clue in The Irish Independent.
