>> train people more. You hire them at lower qualifications, and educate them in house.. > ... they learn and then leave, because if you were able to pay them the market rate you would've not been training them in the first place (considering the context of your comment). As an employer, you're going to have to pay market rate for the skills you need, one way or another. If you do that and your employees still want to quit after their training, then your organization has more dysfunctions that you need to fix.
