While AI offers significant opportunities for businesses in Pembrokeshire, it also presents new challenges for employers navigating employee relations issues. JCP Solicitors’ specialist Employment Law team shares on advice on dealing with AI-generated grievances.
AI-generated grievances: a growing workplace reality
A recent survey of more than 900 HR and business professionals found that 70% of employers had seen an increase in grievances they suspected were AI-assisted, while only 12% felt confident that their managers could handle those grievances appropriately.
Anyone involved in employee relations will recognise the trend. A grievance that might previously have been a two-page summary of concerns can now arrive as a detailed document citing legislation, case law and lengthy allegations. The sophistication of the document can sometimes make the grievance appear more serious or complex than the underlying workplace issue.
However, employers should be careful not to become distracted by the style or length of the document. The focus should remain on identifying the actual concerns being raised by the employee and investigating those concerns fairly and objectively. A grievance investigation remains a fact-finding exercise, regardless of whether the grievance was drafted by the employee, a trade union representative or an AI tool.
Importantly, employers should avoid making assumptions that AI-generated content is exaggerated, inaccurate or submitted in bad faith. The legal obligations remain unchanged. The Acas Code expects employers to investigate grievances reasonably, keep an open mind, gather relevant evidence and provide a fair opportunity for employees to explain their concerns.
The challenges for employers
As AI becomes more prevalent in the workplace, employers are likely to encounter a number of recurring difficulties.
First, managers may struggle to assess complaints that appear highly legalistic or unusually sophisticated. This can create a risk that genuine concerns are overlooked or, conversely, that managers become overly defensive.
Secondly, AI can increase the volume of information generated during workplace disputes. Investigators may need to review longer grievances, larger quantities of correspondence and extensive supporting material.
Thirdly, organisations must carefully consider data protection and confidentiality. Grievance investigations often involve sensitive personal data, and employees should be discouraged from uploading confidential workplace information into public AI tools without authorisation.
Finally, employers need to ensure that AI complements human decision-making rather than replacing it. When it comes to grievances, disciplinary matters, discrimination concerns and reasonable adjustments, legal liability remains with the employer.
Action points for employers
As workplace AI use continues to increase, employers may wish to consider the following:
1. Review your policies
Ensure AI use is addressed within relevant workplace policies, including data protection, confidentiality and acceptable use policies.
2. Train managers
Managers should understand how AI is being used by employees and how to respond appropriately to AI-assisted grievances.
3. Focus on the issue, not the document
Whether a grievance runs to two pages or twenty, identify the core concerns and investigate those issues proportionately.
4. Maintain procedural fairness
Follow the Acas Code and your internal procedures. AI has not changed the legal requirements for a fair grievance process.
5. Keep humans in the decision-making process
AI can support HR and management decisions, but it should not replace human judgement, particularly where employee relations issues are concerned.
Looking ahead
AI is unlikely to disappear from workplace relations. For employers, the challenge is not to resist AI but to adapt to it.
Ultimately, whether a grievance is written by an employee, a solicitor, a trade union representative or an AI platform, the underlying principle remains the same: employers should focus on understanding the concern, investigating it fairly and working towards an appropriate resolution.
