Employer turned up yours truly’s CV (6)
I believe the answer is:
resume
'cv' is the definition.
'employer turned up yours truly's' is the wordplay.
'employer' becomes 'user' (I've seen this before).
'turned up' says the letters should be written backwards.
'yours truly' becomes 'me'.
'user' backwards is 'resu'.
'resu'+'me'='RESUME'
(Other definitions for resume that I've seen before include "proceed" , "Carry on where one left off" , "Continue after pause" , "Abstract" , "Begin activity again" .)
