Short-time worker not on time to produce mould (8)
I believe the answer is:
template
'mould' is the definition.
(thesaurus)
'short-time worker not on time' is the wordplay.
'short-time worker' becomes 'temp' (I've seen this before).
'not on time' becomes 'late' (I've seen this before).
'temp'+'late'='TEMPLATE'
'to produce' is the link.
(Other definitions for template that I've seen before include "Pattern for document etc" , "original design" , "Shaped pattern" , "Pattern for cutting out shapes" , "Design model" .)
