Visier finds that when a voluntary resignation occurs, employees on their team are 9.1% more likely to leave. They are 7.7% more likely to leave after an involuntary resignation occurs on their team. Other key findings from the report include:

Smaller teams are most at risk of turnover contagion. Employees who work on teams of two are 25.1% more likely to resign after a team member quits. Employees who work on teams of three to five are 12.1% more likely to resign after a team member quits, while employees on teams of six to 10 are 14.6% more likely to quit.
Turnover contagion can cross from one quarter to the next: The moment an employee resigns, the risk of turnover contagion for other members on the team lasts for 135 days. For "involuntary turnover," the time window is shortened to 105 days.
Turnover contagion peaks around 70 days after the first resignation. The moment an employee resigns, the risk of turnover contagion for other members increases. The critical timeframe for turnover contagion is around 45 days and peaks at 70 days after the initial resignation

"Our findings that are based on actual, live employee events data validate what has long been suspected: Among other possible reasons, people do indeed leave an organization in reaction to their team members' resignation, because such important events do not happen in isolation but within the social setting of a work group or team," the report concludes. "Our analysis shows that team members of a resigning employee are at least 9.1% more likely to quit within 135 days of their colleagues' resignation, an effect that is stronger for smaller teams between two and 10 team members and which peaks around 70 days after the first person resigned.
