Serve alcohol in error - this is an adolescent looking for work (6-6)

I believe the answer is:

school-leaver

'an adolescent looking for work' is the definition.

'serve alcohol in error' is the wordplay.
'in error' indicates anagramming the letters.
'serve'+'alcohol'='servealcohol'
'servealcohol' with letters rearranged gives 'SCHOOL-LEAVER'.

'this is' is the link.

(Another definition for school-leaver that I've seen is " One finishing basic education".)

I've seen this clue in The Independent.
