Working with assignment following pay cut (2,10)

I believe the answer is:

in commission

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

'working' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?

'assignment following pay cut' is the wordplay.
'assignment' becomes 'mission' (mission is a kind of assignment).
'following' says to put letters next to each other.
'pay' becomes 'income' (I've seen this in another clue).
'cut' means to remove the last letter.
'income' with its final letter taken away is 'incom'.
'mission' put after 'incom' is 'IN COMMISSION'.

'with' acts as a link.

Can you help me to learn more?

(Another definition for in commission that I've seen is " In usable or working condition".)

I've seen this clue in The Times.
