Attractive taking on new employee (8)
I believe the answer is:
engaging
This clue is a double definition.
'attractive' is the first definition.
('engaging' can be similar in meaning to 'attractive')
'taking on new employee' is the second definition.
(Other definitions for engaging that I've seen before include "Attractive or charming - getting married?" , "Attacking" , "Taking into employment" , "Winsome" , "coming together" .)
