Employees are turning to generative AI to draft lengthy, “lawyerly” grievances, putting strain on the HR teams asked to respond to them. How should employers deal with the increased length and number of grievances, and what should they do about all those (sometimes dubious) case references?

---

Many employers are asking their employees to adopt generative AI tools at work. It isn’t a surprise, therefore, that employees are increasingly using the same tools to draft their grievances. Although AI tools have the potential (if used in the right way) to help employees organise their thoughts, and express concerns with more clarity and structure, their use can also present challenges for employers. In this article, we explore these challenges and offer some top tips for HR teams tasked with responding to AI generated grievances.

The challenges of AI-drafted grievances

Whilst the complaints and issues may not have changed, AI has made some grievances more difficult for HR to deal with and creates additional challenges:

• Volume and structure – Grievances drafted using AI are often extremely lengthy. The content will of course depend on the quality and clarity of the prompts, but experience indicates that AI generated grievances can be repetitive and lack a clear structure. Following the arguments can be difficult.
• Complex and legalistic – In the pre-AI world, grievances typically focused on factual allegations that the employer needed to investigate. However, AI can add a layer of complexity by introducing legal arguments. That said, AI tools often invent or misapply case law. Complaints littered with case and statute references may look impressive at first glance, but there is a chance that these are irrelevant, or even entirely false.
• Reduced realism – AI-generated grievances often contain exaggerated language and broader accusations, lacking the natural restraint of a manually written complaint. Unlike the process of drafting a grievance by hand, AI can produce large volumes of text that may be copied without close review—leading to strong claims that reflect the tool’s suggestions more than the employee’s actual intent.
• Data risks – If an employee uses a public AI platform to help produce their grievance, there is a risk that they will input sensitive company or personal data. To mitigate this, employers should implement clear policies governing the use of AI and provide all staff with training on responsible usage.
• Optimistic advice – It’s quite likely that an employee who uses AI to help them write a grievance will also be looking to the tool for legal advice or to assess their chances at tribunal. However, AI often tells users what they want to hear rather than providing a balanced and accurate assessment. This means that employees could be getting an overly optimistic view of their prospects of success, a potential barrier to resolution or financial settlement.

How should employers respond?

Employers should adopt a two-part strategy: 1) reducing the chance of formal grievances being raised in the first place; and 2) improving their response strategy when one is received.

Mitigation – limiting the number of formal grievances

Every employer’s priority should be seeking to ensure that employees resolve their issues informally and promptly whenever appropriate. Early intervention can often resolve concerns before they develop into formal grievances. It is essential that HR and management build a positive and supportive workplace culture and act effectively when conflicts arise. Employers should ensure that:

• Grievance policies emphasise informal resolution and outline that often the best and fastest way to resolve problems is to raise them informally. Policies should assist employees in doing this by, for example, signposting employees to discuss the issue with their manager or a member of the HR team.
• They prioritise creating a workplace culture that encourages open communication, rather than punishing it.
• They have clear pathways for employees to raise concerns or issues about those in their reporting line, without fear that doing so will lead to them facing detriment.
• Management and HR are trained and empowered to deal with issues early and effectively.

Top tips for employers responding to AI generated grievances

1. Use face to face meeting where possible

In AI-drafted grievances it can be unclear which parts of the grievance are strongly held, and which are AI-suggested additions. Engaging directly with the employee is likely to be the most effective strategy for understanding what the complaint centres around.  Therefore, it can be helpful to hold a meeting with the employee as soon as possible after the grievance is raised.

Dealing with the volume of content is also likely to be a challenge so preparation for that meeting is likely to be key. If the grievance is particularly lengthy or complex, narrow the grievance down into what appear to be the key concerns.  At the meeting, the employee should be asked to explain in their own words what the main complaints are and how the issues fit together. At the end of the meeting, a summary of the key points should ideally be agreed with the employee.

More generally, the grievance process should be focussed around meetings, rather than relying on written correspondence. This approach limits further AI generated correspondence distracting from the core issues in the employee’s grievance and helps ensure that the true reactions/recollections of any witnesses are captured. However, it’s important to remember to keep detailed notes of all meetings held. 

2. Provide training to managers and HR

An AI generated grievance is likely to be daunting in both length and the forcefulness of the language. Providing training to managers and HR professionals on how to spot signs of AI generated grievances could therefore be helpful. This training can help teams respond to grievances more effectively, meaning they are less likely to be overwhelmed.

3. Don’t be tempted to respond point-by-point

Whilst it can be tempting to respond to grievances on a point-by-point basis, this is unlikely to be the best approach, particularly with AI generated grievances that are lengthy and legalistic. Taking this approach can be time consuming and encourage further AI-generated lengthy responses. The best approach is to clarify and summarise the employee’s key concerns and limit your response to addressing the substantive matters that are relevant.

4. Remember the basics still apply

An AI-generated grievance is still a grievance. Employers’ obligations do not change, and they need to ensure that they:

• Follow the ACAS Code.
• Run a fair procedure – investigate promptly, meet with the employee bringing the grievance, come to a decision and provide a right to appeal.
• Remember that their investigation will likely be disclosable in any resulting litigation.

These obligations apply regardless of whether the grievance was drafted using AI and, if the matter results in litigation, an Employment Tribunal can adjust any award made by up to 25% for unreasonable failure to comply with the ACAS Code.

Looking ahead 

The use of AI in employment processes is only set to increase, and employers are likely to encounter these issues more frequently in the future. In addition to a rise in AI-generated grievances, we are seeing employees turn to AI tools to help formulate arguments and draft documents during redundancy consultation processes and employment tribunal proceedings. Many of the risks, considerations, and practical tips outlined above will be equally relevant when responding to these developments.
