Employing the lady inside with conducting (8)
I believe the answer is:
ushering
'conducting' is the definition.
(ushering is a kind of conducting)
'employing the lady inside' is the wordplay.
'employing' becomes 'using' ('use' can be a synonym of 'employ').
'the lady' becomes 'her' (her refers to a woman).
'inside' means one lot of letters goes inside another.
'using' placed around 'her' is 'USHERING'.
'with' acts as a link.
(Other definitions for ushering that I've seen before include "Showing to a seat" , "Showing people to their seats" , "Taking people to their seats" , "putting one in one's place" , "working as escorts" .)
