Stay connected to talent. Not only will you remind this ex-employee their opinion is still of value to your organization and you care, you also increase the opportunity of this talented individual returning to your organization with additional skills and knowledge. Further to have a former employee speak highly of your organization may lead to referrals of talent as well. Quite often people stay within the same industry and their opinion is told over and over again to others.
By taking this step you also gather competitive industry data. The grass is not always greener.
Distanced from the emotion of leaving and secure in their new position, the information shared will be significantly different. This ex-employee will almost act as an advisor and is encouraged to be a ‘champion’ of your organization. They know your company is taking steps to learn and improve their own performance.
