It relates to reason for employing casual (6)

Ross

I believe the answer is:

causal

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

'it relates to reason for' is the definition.
The definition suggests a singular noun but the answer is not.

'casual' is the wordplay.
'casual' can be anagrammed to 'CAUSAL'.
Though, I'm unsure how this is indicated.

'employing' acts as a link.

Can you help me to learn more?

(Other definitions for causal that I've seen before include "Producing an action" , "Producing an effect" .)

I've seen this clue in the Irish Times.
