Split in duties after reorganisation (8)

I believe the answer is:

disunite

'split' is the definition.
(disuniting is a kind of splitting)

'in duties after reorganisation' is the wordplay.
'after reorganisation' indicates anagramming the letters.
'in'+'duties'='induties'
'induties' is an anagram of 'DISUNITE'.

(Another definition for disunite that I've seen is " Split".)

I've seen this clue in The Telegraph.
