What could make alarm break out — ignoring a factor of job economics (6,6)

I believe the answer is:

labour market

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

'factor of job economics' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'what could make alarm break out ignoring a' is the wordplay.
'what could make' indicates an anagram.
'ignoring' indicates named letters should be taken away.
'alarm'+'break'+'out'='alarmbreakout'
'alarmbreakout' with 'a' removed is 'larmbreakout'.
'larmbreakout' anagrammed gives 'LABOUR MARKET'.

Can you help me to learn more?

(Another definition for labour market that I've seen is " Supply and demand for workers".)

I've seen this clue in The Times.
