Work schedule incomplete? Nonsense (3)
I believe the answer is:
rot
'nonsense' is the definition.
(thesaurus)
'work schedule incomplete?' is the wordplay.
'work schedule' becomes 'rota' (I've seen this before).
'incomplete?' means to remove the last letter (I've seen 'incomplete' mean this).
'rota' with its final letter taken away is 'ROT'.
(Other definitions for rot that I've seen before include "Gradual decline" , "crumble" , "Decay - rubbish" , "Decay or disintegrate" , "Collapse" .)
