A tidy worker (7)

I believe the answer is:

orderly

This clue is a double definition.

'a tidy' is the first definition.
(I've seen this before)

'worker' is the second definition.
(I know that orderly is a type of Soldier)

(Other definitions for orderly that I've seen before include "Hospital attendant; well behaved" , "Methodical; hospital worker" , "Well-behaved; hospital worker" , "He should leave the ward neat" , "Systematically, not haphazard" .)

I've seen this clue in the Evening Standard.
