Under the Equality Act 2010, employers have a clear duty to address sexual harassment at work quickly and fairly. When a complaint is made, it must be taken seriously, handled with sensitivity, and followed by prompt action. Ignoring the issue can lead to legal claims, reputational damage, and a breakdown of confidence among staff.

A well-implemented policy, timely response, and fair investigation help protect both employees and the organisation. In this article, we explain an employer’s legal responsibilities, outline the practical steps to handle sexual harassment complaints, and highlight ways to prevent future incidents.

Key Takeaways

  • Employers have a legal duty under the Equality Act 2010 to address sexual harassment promptly and fairly.
  • A clear, accessible harassment policy, regular training, and effective reporting channels are essential to prevention.
  • Complaints must be acknowledged quickly, investigated impartially, and handled confidentially.
  • Protecting the complainant from retaliation is a key part of an employer’s responsibility.
  • All actions and decisions should be documented to demonstrate that reasonable steps have been taken.

Understanding Employer Obligations Under UK Law

Under the Equality Act 2010, sexual harassment is described as unwanted behaviour of a sexual nature that undermines a person’s dignity or results in an environment that feels intimidating, hostile, degrading, humiliating, or offensive. This protection applies to all workers, including employees, agency staff, contractors, and job applicants.

Behaviours considered sexual harassment include:

  • Making sexual jokes or comments.
  • Sending sexually explicit messages or sharing graphic images.
  • Unwelcome sexual advances, touching, or propositions for sexual activity.
  • Suggesting sexual favours in exchange for opportunities or to avoid negative consequences.
  • Spreading sexual rumours, leering, or making sexually suggestive gestures.
  • Unwanted posts or messages on social media.
  • Treating someone less favourably because they rejected unwanted sexual advances.

Employers must take steps to prevent sexual harassment. This includes maintaining a robust sexual harassment policy that defines misconduct, provides concrete examples, and details consequences for violations. 

The policy should clearly outline reporting procedures, maintain confidentiality for all parties, and explain disciplinary actions that may result if sexual harassment has taken place. Regular guidance ensures staff know how to make a complaint and what to expect.

An employer can be held legally responsible for harassment carried out by staff if they cannot show they took all reasonable steps to prevent it. This is known as vicarious liability. 

Reasonable steps may include having a clear harassment policy, training staff regularly, and ensuring effective reporting channels are in place.

The Equality and Human Rights Commission (EHRC) and ACAS both provide guidance to help organisations meet these obligations and reduce the likelihood of claims reaching an employment tribunal.

How Employers Should Handle Sexual Harassment Complaints

When a complaint of sexual harassment is raised, employers must act promptly and follow a clear, structured process. The following steps should involve:

Step 1: Respond Immediately

When a harassment complaint is received, acknowledge it in writing within 24 hours. Record all complaint details accurately. Reassure the complainant that retaliation will not be tolerated and that protection is a priority.

Employers must take action promptly to prevent harassment at work and support those who report being sexually harassed.

Step 2: Protect the Complainant

Take reasonable steps to prevent further harm, such as adjusting workplace arrangements or work schedules. Closely monitor for any signs of retaliatory behaviour to ensure the complainant’s safety and wellbeing.

This action reflects an employer’s duty to take reasonable steps and maintain a positive workplace culture.

Step 3: Conduct a Fair Investigation

Assign the investigation to an impartial, trained individual. Collect evidence and obtain statements from relevant witnesses. Maintain a transparent and unbiased process, ensuring that everyone involved is treated with fairness and respect.

Always refer to your harassment policy and guidance from Acas or the Equality and Human Rights Commission (EHRC).

Step 5: Make a Decision and Take Action

Evaluate the complaint in line with your policy and UK law, including the Equality Act 2010. Apply appropriate disciplinary measures, proportionate to the findings. Document every action taken; this is essential for legal protection and shows the employer has taken all reasonable steps to prevent harassment at work.

Step 6: Communicate the Outcome

Notify both the complainant and the alleged harasser, respecting confidentiality limits. Clearly explain the appeals process for anyone dissatisfied with the outcome. Transparency reinforces trust and helps prevent future incidents of sexual harassment in the workplace.

Tips for Preventing Future Incidents

Preventing sexual harassment at work is more effective than only responding after a complaint. Employers should take proactive measures to create a respectful and safe workplace. Key actions include:

  • Review and update policies regularly to ensure they meet current legal requirements and reflect the organisation’s culture.
  • Provide mandatory training for all staff, including managers, on acceptable behaviour and how to report concerns.
  • Establish clear, confidential reporting channels so employees feel safe raising issues at an early stage.
  • Lead by example, senior staff should model professional conduct and reinforce that harassment will not be tolerated.
  • Assess workplace culture using surveys, feedback meetings, and routine check-ins to identify potential problems early and address them before they escalate.

FAQs

Employers should implement comprehensive policies that address sexual harassment, provide training for employees, and establish clear reporting procedures. Implementing reasonable measures to prevent harassment can greatly lower the risk of incidents and help maintain a safer workplace.

Workers who face sexual harassment in the workplace should use their employer’s formal complaint process. This usually means reporting the matter to a designated manager or HR representative, making sure the details are recorded, and that the issue is investigated quickly and handled impartially.

Employers are legally obliged to take reasonable steps to handle harassment complaints effectively. This includes thoroughly investigating claims, taking appropriate disciplinary action against offenders, and ensuring the affected employee feels safe and supported throughout the process.

Employers should have policies in place to address sexual harassment by third parties, such as clients or vendors. This can include training staff to recognise and report such incidents and ensuring there are clear procedures for handling complaints involving third-party harassment.

In most cases, you need to begin the ACAS early conciliation process within three months minus one day from the date of the last incident. As the deadlines are strict, it is essential to act without delay.
