As soon as clocked in at workplace, given a hearing (2,5)
I believe the answer is:
on sight
'as soon as clocked' is the definition.
('clock' can mean to see or notice)
'at workplace given a hearing' is the wordplay.
'at workplace' becomes 'onsite' ('on site' can mean at a workplace).
'given a hearing' shows a homophone (sound like).
'onsite' is a homophone of 'ON SIGHT'.
'in' acts as a link.
(Other definitions for on sight that I've seen before include "Once viewed" , "How to shoot dangerous criminal" , "As soon as presented" , "when observed" , "As soon as seen" .)
