Safe to Speak
Why Preventing Sexual Harassment Requires More Than Policy
Would your people feel safe enough to tell you before a problem became an investigation?
On 30th October 2026, the expectations placed on UK employers around preventing sexual harassment will change. The existing preventative duty will be strengthened, requiring employers to take all reasonable steps to prevent sexual harassment at work. For organisations, this understandably brings renewed attention to policies, training, risk assessments, reporting mechanisms and governance. All are important. But focusing solely on the formal architecture of prevention risks overlooking something much harder to capture in a policy document: the real experience of the person who may one day need to use it.
An organisation can have a robust policy, a confidential reporting route and leaders who genuinely believe their doors are open, while still having employees who decide that remaining silent is safer than speaking. That is why the conversation about prevention cannot belong to compliance alone. It is also a conversation about leadership, culture, power and psychological safety, and about what the human brain does when speaking carries perceived social or professional risk.
Prevention begins before there is anything to investigate
Sexual harassment does not necessarily arrive in an organisation as an obvious incident accompanied by a formal complaint. It can develop within a much less visible landscape of everyday behaviour. There may be comments dismissed as banter, boundaries tested and gradually moved, behaviour witnessed but left unchallenged, or small signals that something is wrong but which never quite become significant enough for anyone to intervene. Sometimes managers notice but are unsure what to do. Sometimes colleagues notice and assume someone else will act. Sometimes the person experiencing the behaviour spends weeks or months trying to decide whether what happened was serious enough to say anything at all.
That decision is rarely based on whether they know where to find the organisation's harassment policy. It is much more likely to be influenced by what they have learned about the organisation around them. What happens here when someone challenges a senior person? How has my manager responded when I've raised difficult things before? Have I watched other people speak up and seen them taken seriously? Will I be believed? Could this damage my reputation or career? Will raising it make things better or simply make my working life more difficult?
These are not procedural questions. They are calculations about risk. And this is where neuroscience gives leaders an important lens through which to understand prevention.
The brain doesn't read the policy before deciding whether it feels safe
The human brain is continually interpreting the environment around us and assessing potential threat and reward. In organisational life, those threats do not need to be physical. Status, belonging, certainty, relationships, reputation and social inclusion can all carry enormous weight. Speaking up about inappropriate behaviour can place several of these at risk simultaneously. Imagine challenging someone with greater organisational status. Reporting a colleague who is well liked. Raising an issue involving a high performer. Questioning behaviour that everyone else appears to tolerate. Or telling a manager something that could trigger a formal process whose consequences you cannot predict.
The organisation may be saying, We want you to speak up. The individual's brain may be asking, What could happen to me if I do? That distinction matters.
It also helps explain why psychological safety cannot simply be communicated into existence. People do not feel safe because an organisation tells them they are. They develop a sense of safety through repeated interactions that teach them what happens when they take an interpersonal risk.
A psychologically safe culture is built, or undermined, in remarkably ordinary moments: when somebody disagrees in a meeting, admits a mistake, questions a decision, challenges a more senior colleague, says they are struggling, or raises something a leader would rather not hear. The same is true when someone says, Something happened, and I need to talk to you about it.
An open-door policy tells people that the door exists. What happens when somebody walks through it tells them whether it was genuinely safe to do so.
The first leadership response matters more than we think
This creates an important challenge for organisations because the experience of speaking up is not created by HR alone. It is shaped by every leader who might one day become the first person someone chooses to tell.
And that first response can matter enormously.
A leader hears an allegation and looks visibly shocked. They instinctively defend the person being discussed. They say, “That doesn't sound like them.” They start searching for an explanation. They ask whether the employee is certain they want to take things further. Perhaps they move too quickly into solving the issue when the person first needs to be heard. None of those responses necessarily come from poor intent. Leaders have brains too. Unexpected information, particularly information that challenges our existing view of a person, team or organisation, can trigger our own threat responses and cognitive biases. We instinctively look for certainty. We draw on what we already believe. We want to resolve ambiguity. We may protect relationships, identities or assumptions without consciously realising that we are doing it.
For the person who has taken the risk of speaking, however, those few seconds can communicate something very different: perhaps this wasn't safe to say after all.
That is why preventative capability needs to extend beyond telling managers what the policy says. Leaders need to understand how to regulate their own response, listen without prematurely reaching conclusions, remain curious when information conflicts with what they believe, recognise the influence of status and power, and understand what needs to happen next. In other words, organisations need leaders who are not simply willing to listen, but capable of listening well when what they hear is difficult.
Prevention and investigation are part of the same leadership system
Of course, even the strongest preventative culture will not eliminate every incident. There will be occasions when a concern becomes a formal complaint and an investigation is necessary.
Here, another capability gap can emerge.
Workplace investigations are often treated primarily as procedural processes. Process is essential: fairness, evidence, consistency and legal obligations matter. But a sensitive workplace investigation is also an intensely human environment. People may be operating under considerable uncertainty and stress. Accounts may conflict. Memories may be imperfect. Relationships and reputations may be at stake. Organisational hierarchies can influence how freely people speak. Investigators bring their own assumptions and cognitive biases into the room, however experienced or well intentioned they may be. The challenge is therefore not to choose between humanity and rigour. It is to hold both.
Psychological safety does not mean accepting an allegation without question or compromising fairness to the person being investigated. Equally, investigative rigour does not require removing humanity from the process. Done well, an investigation creates conditions in which people can provide the best evidence they are able to give while the investigator remains objective, evidence-led and open to more than one possible conclusion. That requires more than knowing the stages of an investigation. It requires judgement, self-awareness, skilled questioning, an understanding of bias and behaviour, and the ability to navigate power and emotion without allowing either to determine the outcome. These are leadership capabilities as much as investigative ones.
The investigation should not be where the learning ends
There is a further question organisations should be asking once an investigation has concluded: What has this taught us about the environment in which it happened?
Too often, the organisational objective becomes reaching an outcome, completing the process and closing the file. Yet an investigation can reveal far more than whether a particular allegation was substantiated. It can expose patterns of behaviour that had become normalised. It can reveal where managers lacked confidence to intervene, where employees did not trust reporting routes, where power operated unchecked, or where seemingly isolated behaviours were actually symptoms of something broader within the culture. This does not mean assuming every incident represents organisational failure. It means being sufficiently curious to ask whether there is anything the organisation should learn. Were there earlier signals? Did other people see them? If so, why did nobody challenge them? Did managers know what to do? Were expectations about behaviour genuinely understood? Did employees know how to raise concerns? More importantly, did they believe doing so would make a difference?
The shift from What happened? to What allowed this to happen here? is a significant one.
It moves the organisation from case management towards organisational learning, and from responding to individual incidents towards genuine prevention.
The real test of a speak-up culture
The strengthened preventative duty arriving on 30th October creates a useful moment for organisations to examine their approach. But perhaps the most revealing audit will not begin with the policy folder. It will begin with experience.
Do people recognise inappropriate behaviour before it escalates? Do they see colleagues and leaders challenge it? Do employees believe concerns will be taken seriously regardless of who is involved? Can managers receive difficult information without becoming defensive or rushing to judgement? And if something does require investigation, are the people responsible equipped to combine fairness and evidential rigour with an understanding of the humans involved?
There is also a harder question. What are people in your organisation currently choosing not to tell you?
No policy can answer that. Culture might.
The organisations that make meaningful progress on preventing sexual harassment will undoubtedly need sound policies, appropriate training, effective reporting mechanisms and robust investigative processes. But those things work best inside an environment where expectations are reinforced through everyday behaviour, leaders understand the human dynamics of speaking up, and people have evidence through their own experience and the experience of others - that difficult things can be said. Because ultimately, prevention is not demonstrated by the existence of a policy. It is demonstrated by what happens between people long before anyone needs to use it.
Prevention is cultural. Speaking is human. Responding is leadership. Investigation is capability.
At Unlocq Leadership, this is the conversation we're interested in: not simply whether organisations are prepared to respond when something goes wrong, but whether their leaders and cultures are creating the conditions that make problems less likely to remain unseen in the first place.
This October, our Safe to Speak conversation will continue through Unlocq Thinking and LiteBite Live, bringing together perspectives from across The Collective on psychological safety, prevention, leadership response and investigation capability.
Because if we want safer workplaces, perhaps one of the most important places to start is understanding what makes a human-being decide it is safe enough to speak.
