For years, engagement surveys have been one of HR’s most trusted measures of retention risk.
Scores fall, managers are alerted, action plans are created, and organisations hope they’ve intervened in time.
Sometimes they have. Often, they haven’t.
That’s because engagement is a measure of the present, not a prediction of the future.
Many employees who resign weren’t disengaged when they made the decision to leave. They were still delivering results, collaborating with colleagues and receiving positive performance reviews. On paper, they looked committed. In reality, they had already concluded that their future lay elsewhere.
If organisations want to improve retention, they need to stop relying solely on lagging indicators and start understanding the behavioural factors that shape whether people remain successful, challenged and committed over the long term.
The question is no longer only, “How engaged are our employees?”
It’s “How well does this role continue to fit the person doing it?”
Engagement tells you what has happened. Behaviour tells you what could happen next.
Engagement remains valuable. It provides a snapshot of how employees experience their work today and highlights issues that require immediate attention.
However, engagement should not be confused with prediction.
Gallup’s State of the Global Workplace 2024 found that managers account for approximately 70% of the variance in team engagement. That finding reinforces an important point. Employee experience is heavily influenced by day-to-day management.
It doesn’t answer a different question: who’s likely to resign next year.
By the time engagement scores begin to decline, many of the underlying issues have already existed for months. Employees rarely wake up one morning and decide to leave. Decisions to resign are often the result of a gradual misalignment between the individual and the work they’re expected to do.
That misalignment is where behavioural science becomes valuable.
The employees most at risk aren’t always the least engaged
One of the biggest misconceptions in retention is that unhappy employees leave while happy employees stay.
Reality is more complicated. Consider two high-performing employees.
Both consistently exceed expectations. Both receive strong engagement scores. Both are viewed as future leaders. One remains with the organisation for years. The other accepts an external offer within eighteen months.
Traditional HR metrics struggle to explain the difference. Psychometric and behavioural data often can.
The employee who leaves may no longer feel intellectually challenged. They may thrive on constant learning while their role has become predictable. Their manager’s communication style may conflict with how they naturally process information and feedback. The work itself may simply no longer align with what motivates them.
None of those factors necessarily appear in an engagement survey until it’s too late.
Four behavioural indicators HR should be paying closer attention to
1. Learning agility
Some employees are energised by solving unfamiliar problems, taking on new responsibilities and learning continuously.
When those opportunities disappear, motivation often follows.
High learning agility isn’t simply about developing future leaders. It can also indicate whether someone is likely to outgrow their current role long before they become visibly disengaged.
When an employee has high learning agility, retention conversations should therefore include a simple question:
Have they stopped learning?
If the answer is yes, it may be time to redesign the role, expand responsibilities or explore internal mobility before the employee starts looking elsewhere.
Low learning agility tells a different story. These employees aren’t necessarily flight risks, many are highly engaged in a role that plays to established strengths, and pushing constant novelty on them can do more harm than good.
2. Autonomy fit
Hybrid and flexible working have highlighted an important reality. People perform differently under different levels of structure.
Some individuals flourish when given freedom to organise their own work. Others achieve their best results with regular guidance, clear expectations and frequent interaction.
Neither preference is better.
Problems arise when the working environment consistently conflicts with how someone naturally operates.
An employee who values independence may feel constrained by excessive oversight. Someone who prefers structure may struggle in highly autonomous environments.
The issue isn’t flexibility. It’s behavioural and motivational fit.
3. Cognitive challenge
Much has been written about burnout. Far less attention is given to boredom.
Employees whose capabilities significantly exceed the demands of their role often become disengaged despite continuing to perform well. They complete their work efficiently, receive positive feedback and quietly begin exploring new opportunities.
High performers don’t always leave because work is overwhelming. Sometimes they leave because it no longer stretches them.
Understanding the relationship between an individual’s cognitive capability and the complexity of their role provides HR with a valuable early indicator that traditional engagement measures often overlook.
4. Manager compatibility
The phrase “people leave managers, not organisations” has become a familiar HR cliché. Like many clichés, it contains an element of truth.
The quality of the manager-employee relationship influences communication, trust, development and day-to-day motivation.
Yet organisations typically evaluate that relationship only after problems emerge through engagement surveys, grievances or exit interviews.
Behavioural insight offers an opportunity to be more proactive.
Understanding communication preferences, decision-making styles and feedback needs before leadership appointments or organisational restructuring can help reduce avoidable friction and strengthen working relationships from the outset.
The objective isn’t to create identical personalities. It’s to create environments where different personalities can work together effectively.
Retention should become part of workforce planning, not just employee experience
Retention discussions often sit within employee engagement programmes. Perhaps they belong somewhere else. Every resignation affects more than headcount.
Critical knowledge walks out the door. Customer relationships are disrupted. Projects slow down. Successors aren’t always ready.
Recruitment costs increase, while productivity often falls during the transition.
Viewed through that lens, retention becomes a workforce planning issue as much as an employee experience issue. The organisations making progress aren’t replacing engagement surveys.
They’re adding another layer of insight.
They combine employee sentiment with objective behavioural data to better understand why people succeed, where they may struggle and how roles, managers and development opportunities can evolve before resignation becomes the preferred option.
Three questions every HR leader should be asking
Before your next retention review, consider asking:
- Is this employee still being challenged by the work they’re doing?
- Does their manager create the conditions in which they’re most likely to succeed?
- Has the role evolved in a way that still matches the individual’s behavioural strengths and motivations?
Those questions move the conversation beyond engagement scores and towards understanding long-term fit.
Looking beyond today’s engagement score
Engagement surveys remain an important part of every HR strategy.
They tell organisations how employees feel.
Behavioural science helps explain why they feel that way and whether those underlying conditions are likely to change.
In an environment where critical skills remain scarce and replacing experienced talent is increasingly expensive, waiting for engagement scores to decline is a reactive strategy.
The opportunity for HR is to identify behavioural misalignment before it becomes a resignation.
Retention isn’t simply about making people happier at work.
It’s about ensuring the right people remain in the right roles, supported by the right managers, with opportunities that continue to challenge and develop them.
That’s where long-term retention begins.
