Break down a working schedule (4)
I believe the answer is:
rota
'working schedule' is the definition.
'rota' can be an answer for 'schedule' (I've seen this before). I'm not sure about the 'working' bit.
'break down a' is the wordplay.
'break down' becomes 'rot' (I've seen this in another clue).
'rot'+'a'='ROTA'
Can you help me to learn more?
(Other definitions for rota that I've seen before include "Register of names for duties" , "Task list, roster" , "List of duties to be done, or people to do them" , "supreme Catholic court" , "Work roster" .)
