Psychological Safety at Work: Why Workers Don't Speak Up and How to Fix It

Understanding the "silence gap" in workplace safety and building a culture where employees feel safe to raise concerns

A significant "silence gap" is threatening workplace safety across the UK and globally. Research published in 2026 by Mental Health First Aid England reveals that 45% of UK employees do not feel safe raising mistakes or highlighting risks to their employers. Nearly half (49%) don't feel comfortable expressing their needs at work, more than a third (35%) don't feel safe asking for help, and 15% say they have made preventable mistakes because they felt unsafe speaking up.

These statistics represent a critical vulnerability in modern workplace safety. When fear of judgment silences a workforce, hazards go unreported, near-misses are hidden, and critical errors go unchallenged. The consequences can be serious injuries, fatalities, and catastrophic incidents that could have been prevented if someone had felt able to speak up.

This guide explores the concept of psychological safety, why it matters for workplace health and safety, what the research tells us about the current state of speaking-up culture, and how organisations can build environments where employees feel safe to raise concerns. For health and safety consultants supporting clients with culture change, and for organisations seeking to strengthen their safety performance, understanding psychological safety is essential.

What Is Psychological Safety?

Psychological safety is a term coined by Harvard Business School professor Amy Edmondson. It describes a shared belief held by members of a team that the team is safe for interpersonal risk-taking. In a psychologically safe environment, people feel comfortable admitting mistakes, asking questions, raising concerns, and offering ideas without fear of embarrassment, punishment, or ridicule.

Psychological safety is not about being nice or avoiding difficult conversations. It is about creating conditions where people can be candid, where bad news travels fast, and where problems are surfaced early when they can still be addressed. In safety-critical environments, this is essential. The worker who notices a frayed cable, the operator who spots an unusual reading, the team member who realises a procedure isn't being followed correctly: these individuals hold information that could prevent incidents. But they will only share that information if they feel safe to do so.

Why Psychological Safety Matters for Workplace Safety

Every investigation into major industrial disasters reveals missed opportunities where someone knew something was wrong but didn't speak up, or spoke up but wasn't heard. The Piper Alpha disaster, the Deepwater Horizon explosion, the Boeing 737 MAX crashes: in each case, post-incident analysis revealed that warning signs existed but were not effectively communicated or acted upon.

Psychological safety directly impacts workplace safety in several ways:

• Near-miss reporting: Workers are more likely to report near-misses when they trust that doing so won't result in blame or punishment. Near-miss data is essential for identifying and addressing hazards before they cause harm.
• Hazard identification: Frontline workers often have the best knowledge of actual working conditions. If they feel safe to speak up, they can identify hazards that management may not see.
• Error reporting: Understanding errors and their causes is essential for learning and improvement. When people hide errors, organisations lose the opportunity to fix underlying problems.
• Challenging unsafe decisions: Sometimes safety requires someone to say "stop" or to question a decision made by someone more senior. Without psychological safety, such challenges rarely happen.
• Continuous improvement: A culture where people can suggest improvements leads to better procedures, better equipment, and better outcomes.

The Current State: What the Research Tells Us

The 2026 MHFA England research surveying 2,000 UK working adults paints a concerning picture of psychological safety in UK workplaces.

Key Findings

• 45% of employees do not feel safe raising mistakes or highlighting risks
• 49% don't feel comfortable expressing their needs at work
• 35% don't feel safe asking for help
• 15% have made preventable mistakes because they felt unsafe speaking up

That last statistic is particularly significant. One in seven workers admits that stress and fear have already led to preventable mistakes. These are not theoretical risks; they are errors that have already occurred and could have been avoided if workers had felt able to speak up, ask questions, or seek help.

The Safety Implications

In safety-critical environments, these numbers represent serious risk. If 45% of workers don't feel safe highlighting risks, how many hazards are going unreported? If 35% don't feel safe asking for help, how many workers are undertaking tasks they don't fully understand? If 15% have already made preventable mistakes, how many near-misses and incidents have occurred that could have been avoided?

As Sarah McIntosh, Chief Executive of MHFA England, noted: "When people don't feel safe flagging a risk or asking a question, mistakes slip through, quality suffers, and the bottom line and wellbeing take a hit." In an era of rapid change, including new technologies and evolving work patterns, human judgment remains a critical safety net. But that safety net only works if people feel able to use it.

The International Perspective on Psychological Safety

The challenge of psychological safety is not unique to the UK. Research from around the world shows similar patterns, though cultural factors influence both the extent of the problem and effective solutions.

Cultural Variations

National and organisational cultures significantly affect psychological safety. In cultures with high power distance, where hierarchy is strongly emphasised, workers may be less likely to challenge decisions made by superiors. In cultures that emphasise harmony and face-saving, people may avoid raising concerns that could cause conflict or embarrassment. In individualistic cultures, people may be reluctant to admit mistakes that could affect their personal standing.

For global health and safety consultants supporting multinational organisations, understanding these cultural variations is essential. Approaches that work well in one country may need to be adapted for another. The goal remains the same: creating conditions where people feel safe to speak up. But the specific interventions may need to be tailored to local cultural context.

Regulatory Recognition

Regulators are increasingly recognising the importance of psychological safety. In the UK, the HSE's approach to safety culture assessment includes factors related to speaking up and reporting. ISO 45001 emphasises worker consultation and participation, which depends on workers feeling safe to engage. Australia's model Work Health and Safety legislation explicitly requires consultation with workers, which presupposes that workers can speak freely.

In some sectors, psychological safety is explicitly regulated. Aviation has Crew Resource Management and just culture principles. Healthcare has patient safety reporting systems. These sectors have learned that safety depends on people being willing and able to speak up.

Barriers to Speaking Up

Understanding why workers don't speak up is the first step to addressing the problem. Research identifies several common barriers.

Fear of Consequences

Workers may fear that speaking up will result in negative consequences: being blamed, being seen as a troublemaker, being passed over for promotion, or even losing their job. This fear may be based on past experience, on witnessing what happened to others who spoke up, or on assumptions about how management will react.

Hierarchy and Power Dynamics

In strongly hierarchical organisations, junior staff may feel it is not their place to question decisions made by more senior people. They may assume that those above them know better, or that challenging superiors is inappropriate. This is particularly problematic when the person who has spotted a problem is junior and the person who needs to hear about it is senior.

Futility

Workers may not speak up because they believe it won't make any difference. They may have raised concerns in the past that were ignored or dismissed. They may see others raising concerns without any visible response. Over time, this leads to learned helplessness: why bother speaking up if nothing will change?

Uncertainty

Workers may be uncertain whether what they've observed is actually a problem. They may worry about looking foolish if they raise something that turns out not to be an issue. They may not know how to raise concerns or who to raise them with. This is where clear procedures and training become important.

Building Psychological Safety: Practical Steps

The good news, as MHFA England notes, is that psychological safety can be built with the right tools and approaches. Small changes can make a significant difference to whether people feel safe to speak up.

Leadership Commitment

Psychological safety starts at the top. Leaders must:

• Explicitly communicate that speaking up is expected and valued
• Model the behaviour by admitting their own mistakes and asking for input
• Respond positively when people do speak up, even when the news is unwelcome
• Take visible action on concerns raised to demonstrate that speaking up makes a difference
• Hold managers accountable for creating psychologically safe teams

Just Culture

A just culture distinguishes between blameworthy and blameless behaviour. Honest errors and mistakes made in good faith are treated differently from reckless behaviour or deliberate violations. When workers trust that honest mistakes won't be punished, they are more willing to report them. This requires clear principles, consistent application, and trust that the system is fair.

Accessible Reporting Systems

Make it easy for people to raise concerns. This includes clear procedures for reporting, multiple channels (in person, written, anonymous options where appropriate), and assurance that reports will be taken seriously and responded to. Health and safety software can support this by providing accessible reporting tools and tracking responses to ensure concerns are addressed.

Manager Training

Line managers have enormous influence on psychological safety within their teams. From the conversations they have to the way meetings are run, managers shape whether people feel safe to speak up. Training managers in how to create psychological safety, how to respond to concerns, and how to encourage input is essential.

Measuring and Monitoring

What gets measured gets managed. Include psychological safety and speaking-up culture in employee surveys. Track near-miss reporting rates and quality. Conduct health and safety audits that assess not just compliance but culture. Use the data to identify areas for improvement and track progress over time.

Health and Safety Consultants and Software: Supporting a Speaking-Up Culture

Building psychological safety requires systematic approaches. Health and safety consultants and software platforms work together to provide tools that support a culture where people feel safe to speak up.

Digital platforms support psychological safety through:

• Accessible incident and near-miss reporting tools available on mobile devices
• Anonymous reporting options where appropriate
• Tracking of report responses to demonstrate that concerns are addressed
• Feedback loops showing what changed as a result of reports
• Culture survey tools to measure psychological safety
• Health and safety audit modules that assess culture alongside compliance
• Dashboards tracking leading indicators like reporting rates

For international health and safety consultants supporting organisations across multiple countries, integrated software enables consistent approaches to culture measurement and improvement while accommodating different local contexts.
