What are the biggest mistakes organisations make with employee surveys?
Employee engagement surveys are widely used but often don’t achieve much beyond raising expectations that the survey will lead to improvement.
In most cases, the issue isn’t the idea of surveying employees. It’s how the process is designed and handled.
Below are some of the most common mistakes organisations make—and what tends to work better in practice.
Treating the survey as a standalone exercise
One of the most frequent issues is viewing the survey as a one-off activity.
The survey is launched, results are shared, and then attention moves on. Employees quickly notice this pattern, especially if it repeats year after year. This leads to lower levels of trust, decreasing the response rate to subsequent surveys and, of course, wasted money.
In reality, a survey should be part of a broader process of listening, understanding, and responding. The value comes not from the data itself, but from what is done with it.
In our work, the focus is always on how the survey will be used before it is even launched—so that it leads naturally into action, rather than becoming an isolated event.
Asking questions that don’t lead to action
Another common mistake is including too many questions—or questions that are interesting, but not useful. At Protostar, we call this the “So What Test”. If there is no intention to do something with the answers to a specific question, then why ask it?
Surveys can easily become long and unfocused, covering every possible topic without a clear intent. This creates two problems:
- Employees lose engagement while completing the survey
- Leaders receive data that is difficult to interpret or act on
Effective surveys are more selective. Questions are chosen because they will inform decisions and conversations, not simply because they might be useful to know.
This often means taking a more disciplined approach to design, keeping the survey focused on areas where the organisation is willing and able to respond.
Underestimating the importance of trust
If employees are unsure whether their responses are genuinely confidential—or how the data will be used—they are unlikely to answer honestly.
Trust is influenced by several factors:
- How clearly the survey is explained
- Whether anonymity is credible and well communicated
- How previous surveys have been handled
- Obvious anonymity safeguards, for instance, summarising comments rather than reporting on them verbatim.
Organisations sometimes assume trust is already there. In practice, it often needs to be actively built.
A more effective approach is to be clear, transparent, and consistent—so employees understand what the survey is for, how their data will be treated, and what will happen next.
Focusing too much on the data, not enough on interpretation
Survey results can be detailed and complex. It’s tempting to focus on scores, benchmarks, and comparisons.
However, data on its own rarely provides clear answers.
Without careful interpretation, organisations can:
- Overreact to small differences
- Miss the underlying themes
- Focus on the wrong priorities
What tends to matter more is helping leaders understand what the results mean in context, and where to focus their attention.
This often involves guided interpretation, rather than simply presenting data and expecting managers to draw conclusions on their own.
Expecting managers to “own” the results without support
A common assumption is that once results are shared, managers will take ownership and drive action.
In reality, many managers:
- Feel unsure how to interpret the data
- Lack confidence in running follow-up conversations
- Are unclear on what good action looks like
- Take low scores as a criticism of them, and so they ignore the results.
Without support, this can lead to inaction—or superficial responses that don’t address underlying issues.
More effective approaches provide practical guidance and structure, helping managers translate results into meaningful discussions and realistic actions.
Failing to follow through
Perhaps the most damaging mistake is failing to follow through visibly.
If employees take the time to give feedback but see little change, future participation and honesty will decline.
Follow-through does not mean solving everything immediately. It means:
- Acknowledging what has been heard
- Being honest about what will and won’t change
- Showing progress over time (this is vital if you want a high response rate next time)
Consistency here is more important than perfection. While much of this can be done at the corporate level, your line managers might require coaching on how to ensure their teams feel they have been listened to.
What really makes the difference?
Most of these mistakes come down to a simple issue: treating the survey as a tool, rather than a process.
The organisations that get value from employee surveys tend to:
- Design them with a clear purpose
- Communicate openly and build trust
- Support leaders in understanding and acting on results
- Focus on practical follow-through
The survey itself is only one part of that.
If you’re reviewing how your organisation approaches employee surveys, it can be useful to step back and look at the end-to-end process, not just the questionnaire.
