The Grievance You Just Received Is the Best Intelligence Your Business Will Get This Year.

When a grievance lands on an HR manager’s desk, the immediate reaction in most businesses is defensive. Something has gone wrong. Someone is unhappy. There may be a legal risk. The instinct is to contain it: investigate, respond, resolve, close. Treat the grievance as a problem to be managed, and manage it as quickly as procedural compliance allows.

This instinct is understandable. It is also a waste of the most valuable information the business will receive all year. An employee who raises a formal grievance has done something that most of their colleagues will never do. They have identified a problem, documented it in writing, and submitted it through a formal process knowing that doing so carries personal risk. They have, in effect, produced a diagnostic report on a specific aspect of organisational dysfunction and delivered it, free of charge, to the people responsible for fixing it.

The question is whether anyone reads it that way. In most businesses, they do not. The grievance is processed, the outcome is communicated, the file is closed, and the insight it contained is lost. The pattern of which teams generate grievances, about whom, and about what, is never analysed. The systemic issues the grievances reveal are never addressed. And the next grievance arrives, about the same manager, making the same points, six months later.

What Grievances Actually Reveal

An individual grievance is a case. A pattern of grievances is intelligence. The distinction matters enormously, because the value of grievance data is not in any single complaint but in the aggregate picture they paint of where the organisation’s management, culture, and structure are failing.

Consider a business that receives three formal grievances in eighteen months. The first alleges bullying by a department head. The second alleges unfair treatment in a promotion decision within the same department. The third alleges excessive workload and lack of support, again within the same department. Each grievance is investigated individually. The bullying allegation is not upheld because the behaviour described, while abrasive, does not meet the threshold. The promotion decision is found to have followed the correct process. The workload complaint is acknowledged but attributed to business pressures that affect everyone.

All three outcomes may be procedurally correct. And all three may miss the point entirely. Three grievances from the same department in eighteen months is not a coincidence. It is a signal that the department is being managed in a way that is generating formal complaints at a rate that far exceeds the organisational norm. The problem is not any individual grievance. The problem is the manager whose leadership style is producing them, and the organisation’s inability or unwillingness to address that.

Esbee’s management consultancy work frequently begins with exactly this kind of pattern recognition. A client approaches with what they describe as a people problem in a specific team: high absence, high turnover, grievances, poor engagement scores. The diagnostic almost invariably reveals that the people problem is a management problem, and the grievances were the clearest early warning system the business had.

The Manager Nobody Will Confront

The most common subject of grievances in mid-market businesses is a manager who is technically competent, commercially productive, and interpersonally destructive. They deliver results. They also generate a disproportionate volume of complaints, sickness absence, and attrition in their team. The board knows about the complaints. The HR team has raised concerns. And nothing changes, because the commercial contribution appears to outweigh the people cost.

This calculation is almost always wrong, but it is wrong in ways that are difficult to quantify in the same reporting framework that makes the commercial contribution visible. The revenue the manager generates appears on the P&L. The cost of the attrition they cause, the recruitment fees, the lost productivity during vacancies, the institutional knowledge that walks out the door, the legal costs of grievances and potential claims, does not. The result is an implicit decision to tolerate the behaviour because the visible number outweighs the invisible one.

An HR MOT conducted by Esbee includes an assessment of grievance and employee relations patterns precisely because these patterns are the most reliable indicator of management capability gaps that the organisation is not addressing. A business that has received multiple grievances about the same manager is not experiencing a grievance problem. It is experiencing a leadership accountability problem, and the grievances are simply the most formal expression of it.

A business that receives multiple grievances about the same manager isn’t experiencing a grievance problem. It’s experiencing a management problem that HR hasn’t addressed.

The Grievance That Arrives During a Restructure

There is a specific scenario that generates more anxiety in HR teams than almost any other: a grievance raised during a restructuring or redundancy process. The timing feels tactical. The subject matter often overlaps with the restructuring itself. The instinct is to dismiss it as an attempt to delay or disrupt the process.

This instinct is dangerous. The ACAS Code of Practice on Disciplinary and Grievance Procedures does not contain an exception for grievances raised during restructuring. The grievance must be investigated, regardless of timing, regardless of the employer’s view of the motive, and regardless of the overlap with other processes. An employer that fails to investigate a grievance because it was raised during a redundancy process is creating a procedural unfairness that will be examined with considerable interest by a tribunal.

More importantly, a grievance raised during restructuring may contain information that is directly relevant to the fairness of the restructuring itself. If the employee alleges that the redundancy selection criteria are being applied unfairly, or that the consultation process is not genuine, or that the pool definition has been drawn to target specific individuals, those allegations deserve investigation not because the employee has a legal right to raise them, though they do, but because they may be correct. And if they are correct, discovering that during the process, when it can be corrected, is vastly preferable to discovering it in a tribunal, when it cannot.

At Esbee, we advise clients to treat grievances during restructuring as an opportunity to stress-test the process. If the grievance identifies a genuine procedural flaw, correcting it in real time strengthens the process and reduces the risk of a successful claim. If the grievance does not identify a genuine flaw, a thorough investigation demonstrates that the process was robust enough to withstand challenge. Either way, the employer’s position is stronger for having taken the grievance seriously.

The ACAS Code and the Uplift You Cannot Afford

The ACAS Code of Practice on Disciplinary and Grievance Procedures is not legislation. It is a code of practice, which means that a failure to follow it is not unlawful in itself. What it does mean, and what too many businesses underestimate, is that a tribunal has the power to increase any award by up to twenty-five percent if the employer has unreasonably failed to follow the Code.

A twenty-five percent uplift on a discrimination claim, a whistleblowing claim, or a constructive dismissal claim is not a marginal adjustment. On a substantial award, it represents a figure that most mid-market businesses would consider material. And the threshold for the uplift is not that the employer failed to follow the Code perfectly, but that the failure was unreasonable. An employer that received a grievance and did not investigate it, or investigated it inadequately, or allowed the investigation to be conducted by someone with a conflict of interest, has unreasonably failed to follow the Code.

The cost of compliance with the Code is modest: a clear grievance procedure, an independent investigation, a meeting with the employee, a written outcome, and an appeal mechanism. The cost of non-compliance, in the form of the uplift alone, is disproportionate. And the reputational cost of a tribunal judgment that specifically criticises the employer’s failure to follow a basic code of practice is considerable, particularly for a business that operates in a sector where employer reputation affects talent acquisition.

The Uncomfortable Conclusion

Grievances are uncomfortable. They consume management time, they create anxiety about legal exposure, and they require a level of procedural rigour that most line managers find burdensome. The temptation to process them quickly, dispose of them efficiently, and move on is entirely understandable.

But the businesses that treat grievances as intelligence rather than inconvenience consistently outperform the ones that do not. They identify management capability gaps earlier, because the grievance pattern tells them where to look. They address structural and cultural problems before those problems generate attrition, absence, and tribunal claims. They build a reputation for taking people issues seriously, which in turn makes the best people more likely to stay and more likely to raise concerns informally before they reach the formal process.

The grievance on your desk is not just a problem. It is a diagnosis. The question is whether you are treating it as something to resolve, or as something to learn from.
