Recommences documents for HR (7)
I believe the answer is:
resumes
'documents for hr' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their -s form.
Perhaps there's an association between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for resumes that I've seen before include "Begins again" , "CVs" , "Carries on" , "Starts or takes up again" , "Restarts" .)
