According to research featured in the Journal of Applied Psychology; nearly 68% of resignations are done in the following manner:
1. By the book (31%) - face to face meeting with the manager, providing a standard notice and an explanation for resignation
2. Perfunctory (23.5%) - shorter face to face meeting with the manager and no explanation for resignation
3. Avoidant (12.7%) - employees tell everyone about their intent to leave except their immediate boss
It's important to note, negative resignation styles tend to shed light on organizational issues that may require immediate attention.
