Which is cheaper? to train staff in customer service in-house or to poach for qualified hands from competitors?

I would agree with answers.. Training in the house could be cheaper !

Thank You

to achieve the long-term business development objectives, preference should be given to in-house training of staff and certain of them will become assets to the company in future. 

it is to cheaper to train staff in-house. 

When you are small, poach. But when you have resources, build in-house training.

Its always cheaper to train the in-house staffs rather than recruiting experienced staffs. But the only drawback is training might consume time depending upon the learning ability of the person.
