Turn one's attention to a day shift (7)
I believe the answer is:
address
'turn one's attention to' is the definition.
'a day shift' is the wordplay.
'a day' becomes 'ad' (I've seen this in other clues).
'shift' becomes 'dress' (I've seen this before**).
'ad'+'dress'='ADDRESS'
(Other definitions for address that I've seen before include "Form of identification for building" , "Place of abode" , "personal details" , "hail maybe?" , "skilfulness or tact" .)
