Perplexed worker possibly overwhelmed by different details (10)
I believe the answer is:
tantalised
'perplexed' is the definition.
(both can mean confused or teased)
'worker possibly overwhelmed by different details' is the wordplay.
'worker possibly' becomes 'ant' (type of ant).
'overwhelmed by' is an insertion indicator (inserted letters get absorbed or overwhelmed).
'different' indicates an anagram.
'details' with letters rearranged gives 'talised'.
'ant' going into 'talised' is 'TANTALISED'.
(Other definitions for tantalised that I've seen before include "Tortured" , "Teased" , "Provoked" .)
