Staff turnover isn't one simple idea. It’s made up of different types of employee departures, and each tells a different story about your company's health.
Here's a quick rundown of the concepts you need.
Key Turnover Concepts at a Glance
| Concept | What It Measures | Why It Matters for Tech Teams |
|---|
| Total Turnover | All employees who left the company for any reason (voluntary, involuntary, retirement). | Gives a broad overview of churn but can be misleading. A high total rate might be from a planned restructuring, not a cultural problem. |
| Voluntary Turnover | Employees who chose to leave, such as for a new job or personal reasons. | This is the important one. High voluntary turnover often points to problems like poor management, burnout, or uncompetitive pay. |
| Involuntary Turnover | Employees who were asked to leave through termination or layoffs. | A spike here could suggest hiring process issues (bad fits) or business challenges that forced redundancies. |
| Attrition | When an employee leaves and their position is not filled. This happens through retirement or role elimination. | Can signal strategic shifts or budget cuts. It’s different from turnover because you are not trying to replace the person who left. |
Understanding these differences is the first step. It helps you move past a single, scary turnover number and start asking the right questions about why people are really leaving.
