Swindle going unchecked puts worker perhaps off (4)
I believe the answer is:
ramp
'swindle' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ramp that I've seen before include "Something that's not on the level" , "Sloping passage" , "Slope for a pram" , "Level-connecting slope" , "Short slope" .)
