Appeals and grievances are two important elements of workplace dispute resolution that UK employers need to understand and manage properly. If handled well, they can strengthen trust and prevent escalation; if managed poorly, they can lead to deeper conflict, formal claims, and tribunal exposure.
As a solicitor advising UK employers on everyday employment law issues, I see a pattern in disputes that reach formal stages. More often than not, there were missed opportunities earlier to listen, respond and resolve issues. My aim in this article is to explain how to approach appeals and grievances thoughtfully and in a way that reduces risk and supports a constructive workplace culture.

A grievance is any concern, problem or complaint raised by a worker relating to their employment. It could be about work relationships, terms and conditions, health and safety, discrimination, or even how management handles certain situations. A properly run grievance process gives employees a clear route to raise issues and gives you a fair means to investigate and respond.
Ignoring or minimising grievances often leads to frustration and mistrust. A worker who feels unheard may escalate the matter, sometimes bringing a claim at an Employment Tribunal. Early and effective handling of grievances thus protects the business and shows you take your people seriously.
Your written grievance procedure should set out how employees raise a concern, how the employer will investigate it, and what outcomes may follow. The ACAS Code of Practice on disciplinary and grievance procedures is widely referenced in tribunal decisions and provides sensible expectations for handling disputes. Following its principles doesn’t guarantee you won’t face a claim, but it does show you have acted reasonably and fairly.
In practice, a good grievance process usually includes the following steps:
Clear communication matters at each stage. Employees should understand what will happen and when, and you should keep good records of meetings, evidence and decisions. These records are useful not only for transparency but also if the matter later comes under external scrutiny.
An appeal is a request by an employee to review a decision they believe is unfair or incorrect. Most grievance policies recognise the importance of appeals, and tribunals regard the right to appeal as a key aspect of fairness. Learning how to handle appeals and grievances well can mean the difference between internal closure and further dispute.
When an appeal is lodged, it should be heard by someone senior to the original decision-maker, or someone who was not involved in the earlier stages. This helps ensure impartiality. The purpose of the appeal is not just to rubber-stamp the first decision but to genuinely reassess the concerns raised and the evidence available.
During an appeal meeting:
At the end of the appeal process, issue a clear written decision setting out the outcome and explanation. This helps the employee understand your reasoning and can reduce the likelihood of further escalation.
There are a few recurring mistakes employers make when dealing with appeals and grievances in the workplace. Being aware of these can help you avoid unnecessary risk.
One common issue is treating informal grievances as trivial and failing to address them early. Even seemingly minor concerns can signal deeper workplace issues that, if ignored, later resurface in formal complaints or disciplinary disputes.
Another frequent problem is inconsistency. If two employees raise similar grievances but receive very different treatment or outcomes without good reason, that inconsistency can create the impression of unfairness and even give rise to claims such as discrimination or breach of contract.
Poor record-keeping also weakens your position. If you cannot show what steps you took and why, it becomes harder to justify your decisions to the employee or, if it goes that far, to an Employment Tribunal.
Consider a scenario where an employee raises a grievance about workload distribution. If you simply tell them to just get on with it, without discussion, they may feel unheard and unhappy. A better approach is to meet, listen to the concern, review relevant data, and agree an action plan where possible. Keep notes of that meeting and follow up on agreed points.
In another example, an employee may appeal the outcome of a grievance that found no evidence of discrimination. An appeal offers a fresh look, perhaps with additional information or a different decision-maker. If you consider the appeal fairly and provide a clear explanation, the employee may feel the process was fair even if the outcome does not change.
These examples underline that appeals and grievances are not just processes to get through; they are opportunities to show fairness and up-date your workplace practices where needed.
Beyond individual cases, appeals and grievances tell you something about workplace culture. If grievances are frequently on similar themes, it may be time to review your policies, communications or management training. Early analysis of patterns can lead to meaningful improvements and reduce ongoing friction.
Good line management also plays a role. Managers who listen, explain decisions, and document key conversations help avoid misunderstandings that later become formal grievances. Training managers on how to chair grievance meetings and handle appeals can transform how disputes are resolved.
Remember that legal protections extend beyond procedural fairness. Employees are protected against detriment or victimisation for raising a grievance, even if the complaint itself is later found to be unfounded. This emphasises the need for sensitivity and professionalism at each step.
Most appeals and grievances can and should be dealt with internally. However, there are times when matters become complex, especially where discrimination, harassment or potential tribunal claims are involved. In those circumstances, early employment law advice helps you weigh risk, consider alternatives, and act with confidence.
Sometimes mediation or external facilitation resolves disputes without formal escalation. Other times you may need to review your policies to ensure compliance with evolving case law and statutory requirements. A little external insight at the right time often prevents bigger problems later.
