My pole dancing initially excited every worker (8)
I believe the answer is:
employee
'worker' is the definition.
(employee is a kind of worker)
'my pole dancing initially excited every' is the wordplay.
'dancing' is an anagram indicator.
'initially' suggests taking the first letters.
The first letters of 'excited every' is 'ee'.
'my'+'pole'='mypole'
'mypole' anagrammed gives 'employ'.
'employ'+'ee'='EMPLOYEE'
(Other definitions for employee that I've seen before include "in work" , "Job-holder" , "Person working for wages or salary" , "Person in office" , "Hand" .)
