Almost empty, accommodating office worker (4)
I believe the answer is:
temp
'office worker' is the definition.
(I've seen this before)
'almost empty accommodating' is the wordplay.
'accommodating' indicates a hidden word.
'TEMP' is hidden within 'almost empty'.
(Other definitions for temp that I've seen before include "relief" , "Short-term worker, in short" , "Casual worker" , "Non-permanent worker" , "Transitory office worker" .)
