How to Negotiate a Salary Increase — Especially When Indexation Disappears

Each year in Belgium, most employees automatically receive an indexation adjustment — a correction of salaries in line with inflation.
Yet few people consider this a real raise. It simply preserves purchasing power.

Now, with the government considering suspending indexation in 2026 as part of broader budget-saving measures, the conversation around pay is about to change. How to negotiate a salary increase in Belgium, could be very challenging.

For many professionals, this could mean facing their first genuine salary negotiation in years — a moment that often blends logic, emotion, and a bit of discomfort.
For employers, it’s equally complex: saying “no” can lead to frustration and demotivation, while saying “yes” to everyone may be financially impossible.

That’s why preparation matters — for both sides of the table.
A well-managed salary discussion can reinforce mutual respect and motivation. A poorly handled one can trigger the opposite: resentment and disengagement.

Here’s how to approach salary negotiations effectively — with confidence, fairness, and strategic awareness.

1. Prepare with Evidence, Not Emotion

The most persuasive argument is built on facts, not feelings.
Before asking for a raise, document your measurable results over the past 12 to 18 months: growth achieved, clients won, efficiencies created, or responsibilities expanded.

Whenever possible, quantify your value:

  • “I grew sales by 15% in my region.”

  • “I implemented a process that saved 30 working hours per month.”

  • “I trained and onboarded two new colleagues who are now top performers.”

Think of your request as a business case, not a complaint. The clearer your value, the easier it is for your manager to justify a decision.


2. Choose the Right Timing — and Secure the Conversation

Timing can make or break your salary negotiation.
Even the strongest case will fall flat if your manager isn’t ready to hear it.

The most strategic moments are:

  • Right after a visible success. When your contribution has just produced clear results, it’s fresh in everyone’s mind.

  • During annual or mid-year reviews. These moments are designed for performance evaluation and goal-setting.

  • When budgets are being defined for the next year. Once budgets are closed, even justified requests are harder to implement.

But what if your manager says: “Let’s talk about that next year”?
That’s where many conversations end — but it doesn’t have to.

Here’s how to keep the dialogue open without creating friction:

Ask for clarity, not commitment.

“I understand now may not be ideal. Could we set a moment to discuss what results or milestones would make a raise realistic in the future?”

Link your timing to business value.

“I’d like to review the results of the project we just completed and discuss how that might influence my role and compensation going forward.”

Make it easy for your manager.
Send a short summary of your results and market benchmarks in advance:

“I’ve prepared a short overview of my recent impact and comparative data. Could we review it together this month?”

If it’s really not possible now, ask for a roadmap.

“I fully understand. Could we agree on three to five measurable goals that would make this discussion relevant again in six months?”

In other words: don’t wait for the perfect moment — create it.
Initiative, clarity, and respect often open doors that hesitation leaves closed.

“Don’t wait for the perfect moment — create it, back it with facts, and own your worth.”

3. Focus on Future Value, Not Past Entitlement

Avoid framing your request as a reward for tenure.
Instead of saying:

“I’ve been here three years, so I deserve a raise,”

say:

“Here’s how I plan to contribute even more next year — and I’d like my compensation to reflect that responsibility.”

This approach reframes the discussion from entitlement to investment. You’re not asking to be rewarded for the past — you’re proposing to be empowered for the future.

4. Know Your Market — and Your Alternatives

Understanding market standards is essential.
Compare your compensation to similar roles in your sector and region using reliable data — industry studies, LinkedIn Salary, Glassdoor, or recruitment insights.

But remember: salary awareness is only half of negotiation power. The other half is your BATNA — your Best Alternative To a Negotiated Agreement.
In simple terms: what happens if the raise doesn’t happen?

Knowing your alternatives gives you composure and choice. It shifts your mindset from asking to deciding.

If a salary increase isn’t possible right now, explore alternatives that create value for both sides:

Financial alternatives

  • A one-time performance bonus or success premium

  • Stock options, profit sharing, or long-term incentive plans

  • A mid-year salary review instead of waiting another year

Non-financial alternatives

  • Additional leave, flexible hours, or remote work options

  • Support for professional training or leadership development

  • A clearly defined career path with promotion milestones

  • A new title or expanded role that increases visibility and future earning potential

Quality-of-life alternatives

  • Commuting compensation, eco-vouchers, or a mobility budget

  • Improved work-life balance measures (such as a four-day week pilot or hybrid model)

Each of these offers real value — financial, professional, or personal.
And for employers, offering such flexibility often costs less than a direct salary increase while maintaining motivation and retention.

If the number on your payslip can’t change right now, ask yourself: what else can?
True negotiation isn’t only about money — it’s about designing an arrangement that respects and sustains value on both sides.

The Bottom Line

Negotiating a salary increase isn’t about greed — it’s about clarity.
Clarity about your contribution, your market value, and your future role in the company.

In Belgium, automatic indexation has long hidden the real value of performance. But if the index disappears, professionals will need to rediscover the skill of negotiating their worth — respectfully, strategically, and with evidence.

Handled well, a salary discussion can strengthen trust, motivation, and engagement.
Handled poorly, it can trigger a cycle of frustration and resignation.

So prepare your facts, know your market, and speak with confidence.
Because when compensation and contribution align, both the employee and the employer win.
