A study by Stepstone, a Belgian recruitment website, indicates the following three top reasons:

• Lack of professional challenges
• Dissatisfaction with responsibilities
• Lack of personal development options

The fact that the salary and conditions are below these three, indicates a well-known fact: money isn’t a motivator for action (either at work or to leave work), but it’s a base condition that should be met.

If you have a problem with personnel turnover and the resulting attrition, the reason is usually not personal. It’s not the employee, his colleagues or his manager that cause him to leave. Take a look at how people interact when decisions are made. Are there hotspots of decision making ?  Can you make people more autonomous by delegating ?  Organisations that involve people in governance and decision making are taking away the three top motivators to leave a company.
