Employer chasing objective consumer (3,4)
I believe the answer is:
end user
'consumer' is the definition.
(end user is a kind of consumer)
'employer chasing objective' is the wordplay.
'employer' becomes 'user' (I've seen this before).
'chasing' means one lot of letters go next to another.
'objective' becomes 'end' (I've seen this before).
'user' after 'end' is 'END-USER'.
(Other definitions for end user that I've seen before include "Ultimate recipient of goods" , "One getting the ultimate enjoyment" , "Person for whom a product is destined" , "Ensured (anag.)" , "Final consumer" .)
