Rubbish people working away at Oxford? (8)
I believe the answer is:
cobblers
'rubbish' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for cobblers that I've seen before include "Rubbish - shoe menders" , "Shoe workers - nonsense!" , "They used the last" , "Sole fitters" , "They make and mend shoes" .)
