Short sheet of paper, something wicked provided during employment (2-7)
I believe the answer is:
in-service
'during employment' is the definition.
'short sheet of paper something wicked' is the wordplay.
'short' means to remove the last letter.
'sheet of paper' becomes 'insert' (piece of paper inserted into a newspaper).
'something wicked' becomes 'vice' (a vice is wicked or sinful).
'insert' with its final letter taken away is 'inser'.
'inser'+'vice'='IN-SERVICE'
'provided' is the link.
(Other definitions for in-service that I've seen before include "(Of training) taking place during employment" , "Domestic servant is - available for use" , "Working as servant; available for use" .)
