Navigating the New Mandate: Employers Prepare for "All Reasonable Steps" in Sexual Harassment Prevention

By Rob Moss
13 May 2026

The landscape of workplace conduct is on the cusp of a significant transformation, as employers across the UK brace for the implementation of a new legal obligation in October 2026. From this pivotal date, organisations will be legally mandated to demonstrate that they have taken "all reasonable steps" to prevent sexual harassment within their operations. This proactive duty marks a substantial shift from previous reactive approaches, demanding a comprehensive and defensible compliance framework.

To assist organisations in navigating this critical transition, Personnel Today, in association with leading learning provider VinciWorks, is hosting a crucial webinar titled "All Reasonable Steps to Prevent Sexual Harassment" on Wednesday, 20 May 2026, at 2:00 PM BST. This session, featuring expert insights from VinciWorks’ compliance and legal specialists, promises to deliver practical, implementation-focused guidance designed to equip employers with the tools necessary to assess their current strategies, identify potential gaps, and build robust preventative measures that can withstand both regulatory scrutiny and potential tribunal challenges.

Main Facts: The Imminent Shift in Employer Responsibility

The forthcoming October 2026 deadline represents a watershed moment for workplace compliance in the UK. The introduction of the "all reasonable steps" mandate places a heightened and explicit duty on employers to actively prevent sexual harassment, rather than merely respond to incidents after they occur. This legal evolution underscores a societal and legislative commitment to fostering safer, more respectful working environments.

The Personnel Today webinar, spearheaded by editor Rob Moss, is specifically tailored to address the practical implications of this new duty. Joined by Nick Henderson Mayo, Head of Compliance at VinciWorks, and Ruth Mittelmann Cohen, Head of Legal Compliance at VinciWorks, the session will delve into the intricacies of designing, developing, and evidencing a compliant approach. This includes a deep dive into critical areas such as assessing third-party harassment risks, a often-overlooked but increasingly vital aspect of workplace safety, and equipping managers with the necessary skills to handle disclosures and conduct investigations effectively and sensitively.

The webinar is not merely an informational briefing but a strategic guide for organisations aiming to construct a coherent framework. This framework is intended not only to meet legal obligations but also to cultivate a workplace culture where sexual harassment is unequivocally unacceptable and effectively prevented. Attendees will gain actionable insights into how these various elements coalesce to form a robust and defensible compliance programme, ensuring their organisation is prepared for the new era of accountability.

Chronology: A Timeline of Evolving Legal Obligations

Understanding the context behind the "all reasonable steps" mandate requires a look back at the trajectory of employment law and societal expectations regarding workplace conduct. The upcoming changes are not isolated but rather represent a logical progression in the pursuit of more equitable and safe workplaces.

The Legal Precedent: Before October 2026

Prior to these new obligations, the legal framework for addressing sexual harassment in the UK primarily rested on the Equality Act 2010. This landmark legislation made sexual harassment unlawful and provided avenues for individuals to seek redress through employment tribunals. Employers have long held a general duty of care and responsibilities under health and safety legislation to protect their employees. Furthermore, the concept of vicarious liability meant employers could be held responsible for the actions of their employees, unless they could demonstrate that they had taken "all reasonable steps" to prevent the discriminatory act.

However, this "reasonable steps" defence was often invoked after an incident had occurred, placing the onus on the employer to prove their preventative efforts post-facto. While some proactive measures, such as anti-harassment policies and basic training, were common practice, the explicit, upfront duty to prevent sexual harassment was less defined and, arguably, less consistently enforced. The March 2026 Personnel Today webinar, which served as "Part 1" of this series, provided foundational knowledge on this existing legal framework, exploring whistleblowing considerations and innovative approaches like bystander intervention, setting the stage for the deeper dive into practical implementation.

The Catalyst for Change: Why "All Reasonable Steps"?

The move towards a more explicit and proactive "all reasonable steps" duty stems from a confluence of factors. High-profile cases of harassment, particularly those brought to light by movements like #MeToo, amplified public and political awareness of the pervasive nature of sexual harassment in various industries. These revelations exposed shortcomings in existing preventative measures and highlighted the need for employers to adopt a more stringent, visible, and comprehensive approach.

Legislative bodies recognised that a reactive legal framework, while providing recourse for victims, was insufficient in fundamentally altering workplace cultures and preventing harm from occurring in the first place. The new mandate, likely stemming from amendments to the Employment Rights Act or related legislation, signifies a proactive shift in legal philosophy. It moves beyond merely penalising wrongdoing to actively compelling preventative action, aiming to foster environments where sexual harassment is genuinely deterred and, if it does occur, is swiftly and effectively addressed through robust internal mechanisms. This legislative evolution places a higher burden of proof on employers to demonstrate systematic and continuous efforts to maintain a harassment-free workplace.

The October 2026 Deadline: A New Era of Accountability

The approaching October 2026 deadline is not just a date on a calendar; it marks the dawn of a new era of employer accountability. From this point forward, organisations will need to clearly articulate, document, and demonstrate the proactive measures they have implemented to prevent sexual harassment. This will require a significant review and potential overhaul of existing policies, training programmes, reporting procedures, and investigation protocols.

The urgency for organisations to act is palpable. Waiting until an incident occurs, or until the deadline has passed, puts employers at significant legal and reputational risk. The upcoming Personnel Today and VinciWorks webinar is therefore incredibly timely, offering a critical opportunity for HR professionals, compliance officers, and senior leaders to gain a definitive understanding of their new obligations and the practical steps required to achieve compliance well in advance of the deadline. It underscores the message that preparedness is paramount, and a strategic, well-planned approach is essential for navigating this new regulatory landscape successfully.

Supporting Data: The Pervasiveness and Cost of Workplace Harassment

While the original article focuses on the upcoming webinar, the imperative for "all reasonable steps" is rooted in the persistent and damaging reality of sexual harassment in the workplace. Understanding the scale and impact of this issue provides crucial context for the new legal mandate and the urgency of effective prevention.

Statistical Landscape of Sexual Harassment

Numerous reports and studies consistently highlight the alarming prevalence of sexual harassment across various sectors and demographics. While specific figures can fluctuate between surveys, the overarching message remains clear: a significant proportion of the workforce has experienced or witnessed sexual harassment. For instance, reports from organisations like the TUC and the EHRC have consistently shown that a substantial percentage of women, and a notable number of men, report experiencing some form of sexual harassment during their careers. This can range from inappropriate jokes and comments to unwanted physical contact and sexual assault.

The impact extends beyond direct victims, creating a toxic environment that affects colleagues, teams, and the entire organisational culture. The insidious nature of harassment often means incidents go unreported due to fear of reprisal, lack of faith in reporting mechanisms, or normalisation of inappropriate behaviour. This "hidden" aspect of harassment underscores the need for robust, proactive preventative measures that build trust and encourage reporting, rather than relying solely on individual courage.

The Business Case for Prevention

Beyond the undeniable ethical and moral imperative, there is a compelling business case for preventing sexual harassment. The costs associated with harassment extend far beyond potential legal fees and compensation payouts, which can be substantial.

• Financial Costs: These include direct legal costs for defending claims, significant tribunal awards (often reaching five and six figures), and potential regulatory fines. Indirect costs are also considerable, such as the expense of internal investigations, employee turnover (recruitment and training costs for replacements), reduced productivity due to low morale and distraction, and absenteeism.
• Reputational Damage: News of sexual harassment allegations or tribunal findings can severely damage an organisation’s public image and brand reputation. In today’s interconnected world, such news spreads rapidly and can lead to a loss of customer trust, difficulty attracting top talent, and negative impacts on shareholder value.
• Non-Financial Costs: The erosion of trust within an organisation is a profound non-financial cost. Harassment fosters a culture of fear, anxiety, and disrespect, leading to decreased employee engagement, innovation, and collaboration. It can also significantly impact the mental health and well-being of employees, leading to stress, depression, and anxiety, which further contributes to absenteeism and presenteeism (being at work but not productive).
• Talent Attraction and Retention: In a competitive labour market, a strong employer brand that prioritises safety, respect, and inclusion is a powerful differentiator. Organisations known for harbouring harassment issues will struggle to attract and retain diverse talent, ultimately hindering their growth and innovation potential.

Challenges in Implementation

Despite the clear need, many organisations face significant challenges in effectively preventing sexual harassment. Common pitfalls include:

• Lack of Clear Policies and Procedures: Ambiguous policies, or policies that are not regularly reviewed and communicated, can leave employees unsure of what constitutes harassment and how to report it.
• Inadequate Training: Generic, one-off training sessions that lack practical application or fail to address power dynamics are often ineffective. Managers, in particular, may lack the specific skills required to identify, address, and investigate harassment.
• Poor Reporting Mechanisms: Systems that are not confidential, accessible, or perceived as impartial can deter victims from coming forward. Fear of retaliation is a major barrier to reporting.
• Ineffective Investigations: Investigations that are not timely, thorough, impartial, or transparent can further traumatise victims and erode trust in the organisation’s commitment to addressing harassment.
• Third-Party Harassment: Many organisations overlook their responsibility to protect employees from harassment perpetrated by clients, customers, or vendors, creating significant vulnerability.

These challenges highlight the critical need for the practical, implementation-focused guidance that the upcoming Personnel Today webinar aims to provide, ensuring employers can move beyond theoretical understanding to demonstrable action.

Official Responses and Expert Guidance: Navigating the New Compliance Landscape

The new "all reasonable steps" mandate necessitates a strategic and informed response from organisations. The Personnel Today webinar, featuring insights from VinciWorks’ leading compliance experts, provides an authoritative roadmap for navigating this complex landscape.

The Mandate of "All Reasonable Steps" in Practice

The phrase "all reasonable steps" is broad, yet it implies a series of tangible actions that employers must undertake. It shifts the burden from merely reacting to incidents to proactively building an environment resistant to harassment. In practice, this will likely entail:

• Robust and Accessible Policies: Clear, concise, and regularly updated anti-harassment policies that are easily accessible to all employees, including contractors and temporary staff. These policies should define what constitutes sexual harassment, outline reporting procedures, and detail the disciplinary actions for perpetrators.
• Comprehensive and Ongoing Training: Not just for employees, but critically for managers and HR professionals. Training should move beyond awareness to skill-building, covering topics like unconscious bias, bystander intervention, effective communication of policies, and how to conduct sensitive and impartial investigations. Training should be tailored, engaging, and regularly refreshed.
• Clear and Trusted Reporting Mechanisms: Multiple channels for reporting harassment, including anonymous options, that are clearly communicated and perceived as safe and confidential. Employees must feel confident that their concerns will be taken seriously and acted upon without fear of reprisal.
• Thorough and Impartial Investigations: A commitment to prompt, fair, and thorough investigations into all allegations. This requires trained investigators, clear protocols, documentation, and communication of outcomes (where appropriate, respecting privacy).
• Preventative Measures Against Third-Party Harassment: Extending the duty of care to protect employees from harassment by non-employees, such as clients, customers, or suppliers. This might involve contractual clauses, codes of conduct for visitors, and clear protocols for employees to report such incidents.
• Culture of Respect: Beyond policies and training, fostering a genuine culture of respect, equality, and zero tolerance for harassment, driven from the top down.

This new mandate demands a shift from a checklist approach to a deeply integrated, continuous effort to embed preventative measures throughout the organisation’s fabric.

Insights from VinciWorks: A Proactive Approach to Prevention

VinciWorks, a recognised leader in compliance and learning solutions, brings significant expertise to this critical discussion. Their approach is rooted in practicality, ensuring that compliance programmes are not only legally sound but also effective in real-world operational contexts.

Ruth Mittelmann Cohen, Head of Legal Compliance at VinciWorks, works extensively with leading UK and global law firms, helping them construct compliance programmes that are "practical, defensible, and fit for the way legal teams operate." Her experience in translating complex obligations into clear, workable approaches across various jurisdictions and functions will be invaluable. Ruth’s insights will focus on the legal nuances of the "all reasonable steps" duty, guiding attendees on how to build a framework that stands up to the most rigorous scrutiny, particularly in a tribunal setting. She will likely emphasise the importance of documentation, consistent application of policies, and the demonstrable efforts made to prevent harassment.

Nick Henderson Mayo, Head of Compliance at VinciWorks, leads corporate compliance strategy and advises senior executives on governance, regulation, and decision-making under uncertainty. His work with organisations, from fast-scaling startups to global enterprises, focuses on leveraging compliance as a "strategic tool for trust, reputation, and sustainable growth." Nick’s contribution will likely address the strategic implications of the new mandate, moving beyond mere legal box-ticking to integrating harassment prevention into broader corporate governance and risk management frameworks. He will provide guidance on how to assess and mitigate risks, particularly regarding third-party interactions, and how to effectively equip managers – the frontline of prevention – to handle disclosures and investigations with confidence and competence.

Together, their expertise will dissect how key elements, from risk assessment to manager training, must fit together seamlessly to form a coherent framework. The focus is explicitly on building a system that can not only pass regulatory checks but also genuinely protect employees and the organisation.

The Role of HR and Leadership

Human Resources professionals are at the epicentre of this transformation. They will be instrumental in developing, implementing, and enforcing the new compliance framework. This requires not only a deep understanding of the legal requirements but also strong leadership, communication, and change management skills. HR will be responsible for:

• Designing and updating policies and procedures.
• Selecting and delivering effective training programmes.
• Establishing and promoting trusted reporting channels.
• Overseeing and ensuring the fairness of investigations.
• Advising senior leadership on compliance strategy and risk mitigation.

However, the success of these efforts hinges significantly on the visible and unwavering commitment of an organisation’s leadership. A top-down approach, where senior executives visibly champion a culture of respect and zero tolerance for harassment, is critical. Leadership buy-in ensures that resources are allocated, policies are enforced consistently, and the message of prevention permeates every level of the organisation. Without leadership’s endorsement, even the most meticulously designed compliance programme can falter.

Implications: Beyond Compliance – Fostering a Culture of Respect

The "all reasonable steps" mandate is more than just a new legal hurdle; it presents an opportunity for organisations to fundamentally reshape their workplace cultures, moving beyond mere compliance to foster environments of genuine respect and psychological safety.

Legal and Reputational Risks of Non-Compliance

The most immediate implication of failing to adhere to the new mandate is significant legal exposure. Organisations that cannot demonstrate "all reasonable steps" to prevent sexual harassment will be highly vulnerable to tribunal claims, potentially facing substantial compensation payouts, unlimited fines, and adverse rulings. The legal costs associated with defending such claims, regardless of the outcome, can be crippling.

Beyond the courtroom, the reputational damage associated with non-compliance can be even more devastating. In an age of heightened social awareness and instantaneous information sharing, an organisation found to be negligent in preventing harassment risks public condemnation, boycotts, and a severe loss of consumer and investor confidence. This can lead to a downward spiral of declining sales, difficulty securing investment, and a tarnished brand image that takes years, if not decades, to repair. The webinar’s emphasis on a "defensible" framework directly addresses these critical risks, providing strategies to mitigate them effectively.

The Broader Impact on Workplace Culture

Conversely, effective implementation of the "all reasonable steps" duty yields profound positive impacts on workplace culture. When employees feel genuinely safe, respected, and confident that harassment will not be tolerated, and that reporting mechanisms are trustworthy, several beneficial outcomes emerge:

• Increased Psychological Safety: Employees feel comfortable expressing themselves, taking risks, and bringing their authentic selves to work, fostering innovation and creativity.
• Higher Employee Morale and Engagement: A respectful environment leads to greater job satisfaction, reduced stress, and a stronger sense of belonging.
• Improved Productivity and Performance: Employees can focus on their work without the distraction and emotional burden of harassment, leading to enhanced individual and team performance.
• Better Talent Attraction and Retention: Organisations with a reputation for integrity and a supportive culture become magnets for top talent and experience lower turnover rates.
• Enhanced Employer Brand: A proactive stance against harassment strengthens an organisation’s reputation as a responsible and ethical employer, appealing to a wider stakeholder base.

These benefits demonstrate that investing in harassment prevention is not merely an expense but a strategic investment in human capital and organisational success. It elevates the conversation beyond legal requirements to one of ethical leadership and sustainable business practices.
