Crossword Genius

I can change into going out, after working (2,6)

Ross

I believe the answer is:

in action

'working' is the definition.
(thesaurus)

'i can change into going out' is the wordplay.
'change' indicates an anagram.
'going out' indicates anagramming the letters (out can mean wrong or inaccurate).
'can' anagrammed gives 'nac'.
'into' with letters rearranged gives 'tion'.
'i'+'nac'+'tion'='IN ACTION'

'after' acts as a link.

(Another definition for in action that I've seen is " Doing something".)

I've seen this clue in the Evening Standard.
