Choose wrong, and you face legal, reputational, and operational risks

Redundancy is rarely just a spreadsheet exercise.

You’re not only reducing headcount. You’re reshaping what your organisation looks like on the other side–what skills remain, what trust survives, and how safely you get through the process without missteps.

In the EU, one bad call during selection can result in serious legal exposure. But beyond compliance, there’s something more dangerous: making choices that quietly harm the business long after the restructuring is over.

That’s why employers must approach redundancy selection with clarity, structure, and real execution control. A clear matrix isn’t about “defending” yourself. It’s about making the right decisions in the first place.

Let’s walk through how to get it right.

What a Redundancy Selection Matrix Does (and Doesn’t Do)

A redundancy matrix is not a legal shield. It’s a decision framework.

You’re not ticking boxes to justify who to let go. You’re applying consistent logic to preserve core capabilities, reduce bias, and protect both people and performance.

Done well, your matrix achieves 3 things:

i) Fairness: Employees are assessed against objective, predefined criteria–not personal opinion.

ii) Transparency: Internal stakeholders and works councils can see how and why decisions were made.

iii) Operational sense: You retain the right skills, experience, and continuity needed for future viability.

But here’s where many employers fail: They focus so hard on formality that they forget the substance. You can follow the “process” perfectly and still end up with gaps in the team that hurt delivery, compliance, or safety.

That’s why criteria selection and weighting are critical.

Criteria That Stand Up to Scrutiny

There’s no universal list of “legal” criteria. Each employer must define their own matrix—but it must be relevant, measurable, and consistently applied.

Common criteria include:

i) Skills and qualifications: Relevant to the future role requirements—not generic or historic.

ii) Performance record: Based on documented reviews, KPIs, or other formal metrics.

iii) Skúsenosti: Years of service may be considered but must be balanced with future needs.

iv) Flexibility and adaptability: Especially relevant in changing environments or where cross-training is vital.

v) Disciplinary or attendance records: Used carefully and only if data is accurate and up to date.

The problem isn’t the criteria themselves–it’s how they’re used. Employers often give equal weight to everything or score people too broadly, which leads to ambiguity.

Instead, the matrix should reflect business priorities. If performance matters more than seniority, score accordingly.

And yes, your weighting can differ by function. Just document your logic and involve HR or legal early.

How Redundancy Matrices Are Scored in Practice

A good matrix isn’t theoretical. It guides real decisions.

Let’s take a simplified example. A manufacturing site needs to reduce headcount in its logistics team. The company defines five criteria, each scored from 0 to 5, with different weights:

Employee A performs better on skills and attendance, while Employee B scores higher on flexibility and performance. When weighted totals are calculated, Employee B edges ahead.

This is not about finding winners and losers. It’s about enabling structured, balanced decisions – and reducing bias under pressure.

Get the Pool Definition Right – or Nothing Else Will Hold

Before applying the matrix, you must define the “selection pool” – the group of employees whose roles are genuinely at risk.

This is one of the most common areas of legal challenge. If the pool is too broad, you risk scoring unaffected employees. If it’s too narrow, you risk accusations of manipulation.

In practice:

If you’re closing one production line, the pool should include all operators from that line – not others

Ak merging teams, the pool may span both functions – but comparability must be clearly defined

Always document why roles are included or excluded. In several countries, works councils or external advisors must review your logic before the matrix is shared.

Avoiding Legal Pitfalls: Mistakes That Get Employers Sued

Selection criteria are only as good as your execution. These are the traps that lead to disputes:

1. Too vague or subjective:

Phrases like “cultural fit” or “attitude” have no place unless clearly defined and evidenced.

2. Hidden bias in scoring:

For example, overemphasising attendance may discriminate against those with disabilities or childcare responsibilities.

3. Inconsistent application:

Using different logic for different teams, or managers scoring people without oversight.

4. Poor documentation:

If you can’t explain your rationale clearly, it won’t hold up to challenge.

You also need to ensure the matrix is applied to a genuine “pool” of affected employees. This is where many managers get confused: you must identify which roles are actually at risk, and who is truly comparable.

Getting this wrong invalidates the entire selection exercise.

Local Labour Law Realities: What You Must Know Across Europe

Redundancy rules vary by country, but core risks are consistent. Still, you need to respect national differences.

Na stránke Nemecko, the works council has co-determination rights. You cannot finalise your matrix without their approval – and you may be required to share anonymised scoring data during consultation.

Na stránke Francúzsko, redundancy criteria must match the “social plan,” and employees have the right to request their individual rationale in writing.

Pre Holandsko, the “last-in, first-out” rule applies by default unless alternative scoring methods are negotiated.

V UK, non-unionised environments still require clear justification. Tribunal risk is real – and notes made during scoring may be legally requested.

Each country differs, but the best employers apply one set of principles: objectivity, transparency, and consistency – regardless of geography.

What Makes a Good Matrix Work in Real Life

An effective redundancy matrix isn’t just a spreadsheet tool. It’s a shared decision system that includes:

• The right criteria: Aligned to the future state of the business.

• Proper weighting: So the most important factors actually influence outcomes.

• Clear documentation: On how scores were assigned, by whom, and with what evidence.

• Checks and balances: Second-layer review by HR or legal to ensure fairness and consistency.

And above all–consistency across sites or units. This is often missed in multinational or multi-site operations.

A matrix used in the German plant should align in principle (if not in exact scoring) with one used in Hungary or Spain, especially if you’re working under a European Works Council.

Tu sa interim transformation leaders from CE Interim often play a quiet but critical role.

When dozens of managers are scoring hundreds of employees under time pressure, consistency breaks fast. A seasoned interim can step in to enforce common methodology, ensure cross-site alignment, and challenge criteria that may look fair on paper but cause chaos in execution.

Balancing Legal, Human, and Operational Realities

Even if your matrix is legally robust, there’s still one more test: does the final outcome make sense for your business?

This is where reality hits. After scoring, if you realise your entire maintenance team or a key compliance function is walking out the door, your matrix hasn’t served you. It’s failed to match risk to strategy.

That’s why leading employers treat the matrix as an input, not a blind output. Some decisions still require executive oversight.

Napríklad:

• You might override matrix scores to retain someone with rare qualifications.
• You might reassign roles rather than eliminate headcount, if it protects critical functions.
• You might pause to engage an interim operations lead to guide the implementation phase before proceeding.

It’s not about “managing risk.” It’s about managing impact.

What to Share With Staff (and When)

You’re not legally obliged to share every score or weighting with employees–but the trend in Europe is toward greater transparency.

If you’re working with unions or a Works Council, you’ll likely need to provide:

• Your matrix framework and justification for each criterion.
• Pooling logic (how you defined which roles were “at risk”).
• Sample anonymised scoring outputs (not individual results unless required).

For affected employees, some companies choose to share their own scores upon request, others do not.

But what matters more is the message around the process: that it was fair, considered, and structured. That’s where your reputation is built or lost.

Final Word: Get the Matrix Right, but Don’t Stop There

The selection matrix is not your protection. It’s your starting point.

It gives structure, accountability, and consistency–but only when built and applied with the right intent. Employers who treat the matrix as a checkbox tool risk losing trust, capability, and sometimes legal ground.

Instead, treat it as a strategy tool: one that protects your business, your people, and your execution during difficult moments.

And if you’re entering unfamiliar territory–whether due to scale, urgency, or cross-border complexity–get outside help. Interim experts who’ve done this before can help you avoid the most expensive mistakes.

You don’t just need a good matrix. You need a good process, the right oversight, and a team who knows what’s at stake.
