Social worker getting one’s child to stop going on slide (4-4)

I believe the answer is:

anti-skid

'to stop going on slide' is the definition.
(designed to prevent slipping or sliding)

'social worker getting one's child' is the wordplay.
'social worker' becomes 'ant' (ants are social insects).
'getting' says to put letters next to each other.
'one's' becomes 'i's' (Roman numeral).
'child' becomes 'kid' (synonyms).
'ant'+'is'+'kid'='ANTI-SKID'

I've seen this clue in The Times.
