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' indicates an anagram.
'initially' suggests taking the first letters.
The first letters of 'excited every' is 'ee'.
'my'+'pole'='mypole'
'mypole' is an anagram of '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" .)
