Be niggardly with work allocation (5)
I believe the answer is:
stint
'work allocation' is the definition.
'stint' can be an answer for 'work' (thesaurus). I'm not sure about the 'allocation' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for stint that I've seen before include "Spot of work" , "Allotted period (of work)" , "Fixed amount - allowance" , "Supply inadequately - fixed period of work" , "one's allotted task" .)
