Leaving child constitutes misconduct (6-2)

I believe the answer is:

goings-on

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

'constitutes misconduct' is the definition.
I can't tell whether this definition defines the answer.

'leaving child' is the wordplay.
'leaving' becomes 'going' (synonyms).
'child' becomes 'son' (male child).
'going'+'son'='GOINGS-ON'

Can you help me to learn more?

(Other definitions for goings-on that I've seen before include "Hanky-panky" , "Suspect events or behaviour" , "Activities, esp. dubious ones" , "Suspicious happenings" , "mischief" .)

I've seen this clue in The Times.
