Insubordination certain, so fuss made (13)

I believe the answer is:

fractiousness

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

'insubordination' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'certain so fuss made' is the wordplay.
'made' indicates an anagram.
'certain'+'so'+'fuss'='certainsofuss'
'certainsofuss' with letters rearranged gives 'FRACTIOUSNESS'.

Can you help me to learn more?

(Another definition for fractiousness that I've seen is " Irritability".)

I've seen this clue in The Telegraph.
