costs for replacement of a Training & Development Professional

Calculate the turnover costs of a Training & Development Professional (non-profit child welfare trainer in the US) assuming the voluntary resignation of a long-term employee in the position. Consider the economic and non-economic costs in your analyses. Describe any difficulty you have coming to an accurate accounting of these costs. What recommendations could you make to the organization to manage these costs? Use at least 2 peer reviewed journal articles to support your analysis. (Ones that I can access) in APA style. If you cannot answer for the specified amount then please don’t bother answering.
