Company worker needs strict control (4,4)

I believe the answer is:

firm hand

'strict control' is the definition.
(I've seen this before)

'company worker' is the wordplay.
'company' becomes 'firm' (I've seen this before).
'worker' becomes 'hand' (hand is a kind of worker).
'firm'+'hand'='FIRM HAND'

'needs' is the link.

(Another definition for firm hand that I've seen is " Strict control".)

I've seen this clue in The Globe and Mail.
