Preventing discrimination at work: an HR guide

For all employers, preventing discrimination is a core legal responsibility mandated by the Equality Act 2010. Compliance requires proactive, documented steps to mitigate legal risk and to leverage the strategic benefits of a truly inclusive and diverse workforce. Organisations must shift their focus from reacting to complaints to establishing a robust, auditable framework built on comprehensive policy, rigorous training and consistent cultural support.

Legal risks and competitive advantage

The Equality Act 2010 establishes a clear statutory obligation for all UK employers to actively prevent discrimination. This imposes a duty to take affirmative measures toward prevention. Employers are responsible for ensuring they do not unfairly discriminate in any aspect of work and must actively do all that is reasonably possible to protect their workforce from discrimination perpetrated by others. This includes upholding a comprehensive ‘duty of care’ to look after the wellbeing of all workers.

The law protects individuals based on nine distinct protected characteristics, including:

• Age
• Disability
• Gender reassignment
• Marriage and civil partnership
• Pregnancy and maternity
• Race
• Religion or belief
• Sex
• Sexual orientation

Discrimination can manifest in four primary ways:

• Direct discrimination (less favourable treatment due to a characteristic)
• Indirect discrimination (when a seemingly neutral practice disadvantages a protected group)
• Harassment (unwanted conduct related to a characteristic)
• Victimisation (negative treatment due to involvement in a discrimination complaint)

The cost of inaction

Failure to implement preventative measures can result in costly consequences. Discrimination claims, which can be made against the individual perpetrator as well as the employer, carry the risk of unlimited compensatory awards and substantial legal defence expenditures. Beyond the financial implications, a failure in preventing discrimination often leads to reputational damage, impacting talent acquisition, staff retention and public confidence.

Understanding the ‘all reasonable steps’ standard

Vicarious liability is the legal rule that makes your company responsible for discrimination committed by an employee, worker, or contractor during the course of their employment. This applies even to things that happen outside the office, like at work parties or on work-related social media. Because of this, managing your HR is vital for legal risk management.

The law essentially treats the employer as responsible by default. The only way for an employer to legally defend itself against a discrimination claim in a tribunal is to prove they took ‘all reasonable steps’ to prevent the discriminatory act from happening.

To establish this defence, you must:

• Systematically implement clear, anti-discrimination policies
• Continuously document staff training on these policies
• Enforce your policies consistently

This creates a strong, auditable paper trail, proving your preventative intent and protecting the business from significant financial liability.

The business value of inclusion

While preventing discrimination is a legal necessity, embracing Diversity and Inclusion (D&I) is also a powerful performance multiplier:

• Diverse teams bring a wider range of perspectives, leading to enhanced decision-making and increased productivity
• Employees in inclusive workplaces are generally more satisfied and engaged
• Building an inclusive and compliant workplace doesn’t require massive resources; even small organisations can take meaningful, low-cost steps

Policies and procedures

The first step in demonstrating your commitment to preventing discrimination is establishing clear, detailed policy documentation. This is fundamental to proving your preventative intent in a legal context.

• You must develop specific policies, including a Bullying, Harassment, and Discrimination policy and an Equality, Diversity, and Inclusion (EDI) policy. These must clearly define unacceptable behaviour and outline the procedure for handling complaints.
• When creating your EDI policy, you must consult with a recognised trade union or employee representative.
• All complaint procedures (grievance and disciplinary) must be full and fair, strictly adhering to the Acas Code of Practice.

A frequent source of inadvertent indirect discrimination lies in the misalignment of core HR policies. It is essential to audit and harmonise all related documents (including policies on absence, recruitment, flexible working, training and working hours) to ensure they do not disadvantage individuals based on their protected characteristics.

For example, a dress code must be sufficiently flexible to accommodate needs related to race, religion (such as turbans or hijabs), sex, or gender reassignment. Similarly, social media policies must clearly state that discrimination in any activity connected to an employee’s work, even if outside the physical workplace, is prohibited.

Training, leadership and cultural embedment

The implementation of robust training programmes represents the single most effective action an employer can take to demonstrate they have met the ‘all reasonable steps’ requirement. Training serves as the mechanism to mitigate vicarious liability by ensuring staff are aware of their responsibilities and the consequences of discriminatory conduct.

The training must be mandatory, regular (e.g., annual refreshers), and fully documented. Modules must clearly define what constitutes acceptable behaviour, clarify the various types of discrimination and inform staff where they can access relevant policies.

Managerial accountability

Managers and supervisors occupy a position of significant influence over team culture and behaviour and often represent the first point of contact for complaints or observed misconduct. Consequently, they must receive specialised, continuous training that equips them not only to recognise and address discrimination swiftly but also to deal with formal complaints. They are expected to role-model inclusive and non-discriminatory behaviours for their teams.

If an employer is found vicariously liable for a manager’s failure to act on a discrimination complaint, the root cause often lies in a deficiency within the manager’s mandatory training or the organisation’s performance management structure. Therefore, embedding anti-discrimination performance into a manager’s core duties is essential to closing the loop on legal risk.

Understanding types of discrimination

To successfully take ‘all reasonable steps’ against discrimination, your organisation must understand the many forms it can take. Discrimination is not always obvious or intentional; it can manifest through systemic practices, microaggressions, or a failure to accommodate specific needs.

Neurodiversity and the duty to adjust

Discrimination related to disability (which includes neurodivergence like Autism, ADHD and Dyslexia) often arises from a failure to comply with the mandatory duty to make reasonable adjustments. This duty requires you to modify a working arrangement or environment if a current practice puts a neurodivergent person at a substantial disadvantage.

Example: A discriminatory act would be refusing to provide a neurodivergent employee with a quiet workspace, thereby failing to remove a substantial disadvantage caused by sensory overload.

Mitigating accent and linguistic bias

Discrimination related to race (which includes nationality and ethnicity) can often surface as accent bias. Negative comments, jokes, or mockery about an employee’s accent can legally constitute harassment and expose the employer to a claim.

Example: Managers must actively challenge any mockery or imitation of a colleague’s accent, and businesses should explicitly avoid requirements for employees to speak with a particular, mandated accent. Training and visible diversification are key preventative measures here.

Accommodating religion and belief

Employers must make reasonable accommodations for employees observing their religion or belief. A failure to do so can lead to a discrimination claim. This requires a flexible and sensitive approach to diverse religious practices.

Example: A discriminatory act would be a manager failing to support a request for adjusted break times or flexible hours for an employee observing Ramadan or other religious practices. Similarly, scheduling mandatory food-related team events during fasting hours is exclusionary. Management must be proactive in offering support and adjusting workload expectations.

Taking ‘all reasonable steps’ involves proactively supporting underrepresented staff and establishing mechanisms for continuous improvement.

Staff networks and employee empowerment

Establishing Employee Resource Groups (ERGs) or staff networks (e.g., for disability, LGBT+, or race equality) is critical for creating a psychologically safe environment and driving change.

ERGs provide a vital voice for underrepresented groups, allowing them to share experiences and raise concerns. They are essential for informing your overall ED&I strategy.

For ERGs to be effective, senior leaders must provide active executive sponsorship, giving network leaders the necessary time and resources. Crucially, clear feedback loops must connect the ERGs, HR, and leadership. Management must actively listen and take decisive steps to resolve issues, significantly strengthening its defence against claims related to poor culture.

Measurement and continuous improvement

The duty to take all reasonable steps is continuous, requiring regular evaluation to ensure your policies work effectively.

• Continuously monitor staff diversity across all roles and pay grades to identify inequities. Also, analyse staff turnover rates to check if any specific protected groups are leaving disproportionately.
• An often-overlooked metric is the analysis of sickness absence records. High or specific patterns of absence among certain protected groups can signal unresolved indirect discrimination or a failure to provide necessary reasonable adjustments.
• When you first establish clear avenues for feedback, expect an initial increase in formal complaints. This is a positive sign, indicating staff have gained confidence in the system and are using it to resolve long-standing systemic problems.

Solidifying your preventative duty

To prevent discrimination under the Equality Act 2010, employers must take steps to avoid unfair treatment and maintain a duty of care for staff. Successfully achieving this requires implementing a culture where proactive inclusion, from accommodating neurodiversity with personalised adjustments to mitigating linguistic discrimination, is an operational standard. This holistic, documented approach minimises legal risk, protects the organisation’s reputation, and ultimately enhances business performance.

The legal reality is that an employer’s strongest defence against a discrimination claim, particularly when facing vicarious liability, is the demonstrable evidence that they have taken ‘all reasonable steps’ to prevent the alleged harm.

As HR specialists, in November 2025 we are hosting a focused and practical workshop for North East businesses, designed to equip employers with the tools and training necessary to meet your legal obligations and successfully defend against discrimination claims.

While our upcoming workshop will equip you with vital tools, effective discrimination prevention is an ongoing commitment. If you have immediate concerns or need expert advice on meeting your legal obligations and fostering true inclusion, contact Sapphire HR today.
