Bullying and harassment at work: what HR needs to know and do

12 June 2025

Bullying and harassment in the workplace can have serious legal, emotional, and organisational consequences. For HR professionals, it's essential to understand your legal obligations - and just as importantly - how to build a culture that prevents these behaviours from taking root.

Here’s an easy-to-follow guide to help you meet your responsibilities, protect your people, and strengthen your culture.

Step 1: Understand the definitions (and the difference)

Bullying is not defined in UK law, but it's widely understood as behaviour that is offensive, intimidating, or undermining—often involving a misuse of power.

Examples include:

  • Persistent criticism

  • Spreading rumours

  • Exclusion from team activities

  • Setting up someone to fail

Harassment, on the other hand, is defined in law. Under the Equality Act 2010, it’s unwanted conduct related to a protected characteristic (e.g. age, sex, race, disability, religion, or sexual orientation) that causes someone to feel intimidated, humiliated, or offended.

It includes:

  • Sexual harassment

  • Derogatory jokes or comments

  • Offensive emails or images

  • Treating someone badly after they reject advances

Both can happen face-to-face, online, by phone, or at work-related events.

Step 2: Know your legal duties

Employers have a duty of care to provide a safe working environment. This includes taking reasonable steps to prevent bullying and harassment.

Recent legal update: Since October 2024, the Worker Protection Act introduced a new duty to proactively prevent sexual harassment. Failing to do so could mean higher compensation awards in tribunal claims.

Other legal risks include:

  • Claims under the Equality Act for discrimination or harassment

  • Constructive unfair dismissal claims

  • Personal injury claims (for mental health harm)

  • Vicarious liability for employees’ actions—even at off-site events

Step 3: Strengthen your policies, training, and culture

To comply with the law and create a respectful workplace, make sure you have:

  • Clear policies on bullying and harassment, with definitions, examples, and reporting steps

  • Training for all staff (especially managers), refreshed regularly and based on real scenarios

  • Multiple reporting routes, so staff can speak up even if the issue involves their line manager

  • Strong leadership—senior staff must lead by example and model respectful behaviour

  • Ongoing monitoring, using staff surveys, exit interviews, and anonymous feedback to identify issues early

Step 4: Act fast and fairly on complaints

Whether a complaint is informal or formal, HR must act promptly and objectively. Here’s how:

Informal route: Sometimes, early resolution like a quiet word or mediation may be appropriate—especially if the person raising the issue agrees.

Formal complaints:

  • Follow your grievance procedure carefully

  • Investigate impartially and gather evidence (e.g. emails, witness statements)

  • Support both the complainant and the accused throughout

  • Take action where needed—this could include training, warnings, or dismissal for serious misconduct

  • Keep detailed records at every stage to show compliance with legal duties

Don’t forget: the investigation process can be stressful. Offering access to employee assistance programmes or temporary work changes can help reduce pressure.

Step 5: Stay ahead of legal and cultural risks

Why it matters:

  • Failure to deal with bullying and harassment can lead to:

  • Tribunal claims with uncapped compensation

  • Loss of talent and morale

  • Reputational damage

  • High turnover and lost productivity

Alarming stats:

  • Most organisations still don’t properly measure or track workplace culture

  • Many lack up-to-date, centralised policies

  • Few offer practical anti-harassment training beyond tick-box e-learning

Don’t be one of them. Regularly review your policies, procedures, and training to ensure they’re effective and legally compliant.

Your HR checklist

  1. Understand and define bullying and harassment, with clear examples

  2. Communicate your legal duties and employer responsibilities

  3. Put in place robust policies, procedures, and practical training

  4. Respond quickly and fairly to all complaints

  5. Keep detailed documentation and follow proper processes

  6. Monitor and proactively manage your workplace culture

Preventing bullying and harassment is not just about avoiding tribunal claims—it's about creating a workplace where people feel safe, respected, and able to thrive. For HR, that starts with clarity, action, and leadership from the top.
