Well-behaved hospital worker (7)

I believe the answer is:

orderly

This clue is a double definition.

'well-behaved' is the first definition.
(I've seen this before)

'hospital worker' is the second definition.
(non-medical worker in a hospital)

(Other definitions for orderly that I've seen before include "Systematically, not haphazard" , "Tidy officer's attendant" , "Methodical, like soldier servant" , "Neatly arranged; hospital attendant" , "Regular - neat" .)

I've seen this clue in The Telegraph and The Sun.
