Muddled info on period of hire (6)
I believe the answer is:
engage
'hire' is the definition.
(I know that hire can be written as engage)
'muddled info on period' is the wordplay.
'muddled info on' becomes 'eng' (I am not sure about this - if you are sure you should believe this answer much more).
'period' becomes 'age' (age is a kind of period).
'eng'+'age'='ENGAGE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for engage that I've seen before include "Become bound; attract" , "Take into employment or occupy attention" , "having to start a battle" , "Take someone on as a worker" , "Take on, hire" .)
