This document discusses ways for managers to identify employees who are most likely to quit. It provides 12 factors managers can look for to determine which employees may be considering leaving: conducting stay interviews; searching online profiles and job boards; examining past job tenure; identifying past reasons for quitting; targeting employees in high-turnover jobs; focusing on new hires; recognizing the impact when colleagues leave; looking for career-damaging events; recognizing ending career stages; watching for major life events; identifying those who feel overdue for advancement; and noticing when top performers feel underutilized. It also suggests additional external and internal approaches managers can use, such as monitoring behaviors and talking to well-informed colleagues.
