Improper accessory? Hold on, teachers work here (9,6)

Ross

I believe the answer is:

secondary school

'teachers work here' is the definition.
(place where teachers work)

'improper accessory? hold on' is the wordplay.
'improper' indicates an anagram.
'accessory'+'hold'+'on'='accessoryholdon'
'accessoryholdon' with letters rearranged gives 'SECONDARY SCHOOL'.

(Other definitions for secondary school that I've seen before include "Educational establishment" , "Where youth's instructed" .)

I've seen this clue in The Independent.
