'training' is the definition.
(I've seen this before)

'opening for executive with routine career coming over' is the wordplay.
'opening for' says to take the initial letters.
'with routine' becomes 'rut' (rut is a kind of routine. I am not sure about the 'with' bit.).
'career' becomes 'run' (I've seen this before).
'coming over' is a reversal indicator.
The first letter of 'executive' is 'e'.
'e'+'rut'+'run'='erutrun'
'erutrun' reversed gives 'NURTURE'.

'for' is the link.
