Wherein chemists are short of labour? (3)
I believe the answer is:
lab
'labour?' is the definition.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lab that I've seen before include "Science workshop" , "In brief, a room for scientific experiments" , "Scientific research space, in short" , "Scientist's workroom" , "Place for experiments" .)
