Resolving interpersonal conflicts at work

Interpersonal conflicts cost European businesses an estimated 359 billion hours of lost productivity per year, according to research by CPP Inc. For HR managers in Belgian organizations, conflict resolution is not a soft skill confined to employee relations specialists — it is a core operational competency with direct financial consequences for every team that experiences it. Left unaddressed, workplace conflicts escalate, damage team morale, drive absenteeism, and produce voluntary departures that cost between 50% and 150% of the departed employee’s annual salary to replace. Addressed early and effectively, conflicts can become catalysts for stronger working relationships and a more honest, resilient organizational culture.

Resolving interpersonal conflicts at work: understanding the causes

Interpersonal conflicts at work can reduce productivity and damage team morale well beyond the individuals directly involved in the disagreement. Often caused by misunderstandings or differing perspectives, such conflicts are inevitable in any organization where people work closely together under operational pressure. What distinguishes high-performing teams from dysfunctional ones is not the absence of conflict but the speed and effectiveness with which conflicts are identified and addressed when they arise.

Conflicts may arise from simple misunderstandings, or from deeper and more structural differences in values, communication styles, and professional goals. Competition for limited resources — whether budgets, equipment, desirable shift patterns, or management attention — and differing approaches to work create ongoing tension that affects productivity and morale across an entire team, not just the individuals in disagreement. Early warning signs include defensive communication patterns, avoidance behaviors, changes in attendance particularly around shared shifts, and a decline in the voluntary collaboration that healthy team performance depends on.

The five stages of workplace conflict escalation

Workplace conflicts follow a predictable escalation pattern. Recognizing the stage of a conflict helps HR managers choose the appropriate level of intervention and avoid either overreacting to early tension or fatally underreacting to late-stage hostility that is approaching the formal grievance threshold.

1. Latent tension: Underlying differences exist but have not yet surfaced as explicit disagreement or observable behavior change
2. Perceived conflict: One or both parties recognize a problem but have not yet spoken about it directly with the other person or with management
3. Felt conflict: Emotional responses emerge — frustration, resentment, anxiety, avoidance behaviors, and reduced voluntary collaboration
4. Manifest conflict: Open disagreement, confrontation, formal complaints submitted, or sustained passive-aggressive behavior patterns
5. Conflict aftermath: Either resolution with restored trust and improved working relationship, or deepened hostility escalating toward formal legal proceedings

Interventions at stages one and two are far less costly, disruptive, and time-consuming than those required at stages four and five. Building an organizational culture where early concerns can be raised safely — without fear of management retaliation or social ostracism from the team — is the single most effective long-term conflict prevention strategy available to Belgian HR managers.

Proven conflict resolution techniques for HR managers

Active listening and structured mediation

The most powerful conflict resolution tool available to HR managers requires no budget and no specialized technology: structured active listening. This means creating a safe, private space where each party can express their perspective fully and without interruption, asking clarifying questions rather than making assumptions or judgments, and reflecting back what has been heard before moving toward any discussion of solutions. Many workplace conflicts that appear intractable dissolve when both parties feel genuinely and completely heard for the first time — because the underlying conflict is often about feeling dismissed, undervalued, or ignored rather than about the surface issue presenting as the problem.

When a manager cannot act as a credibly neutral party — because they are involved in the conflict, have an established relationship with one party, or are perceived as having a predetermined position — an internal HR mediator or external professional mediator should be engaged without delay. Mediation is a structured, confidential process with a high success rate that helps parties reach a mutually acceptable and durably binding agreement without escalating to formal grievance procedures that are costly for all parties.

Interest-based negotiation

Interest-based negotiation focuses on the underlying needs of each party rather than their stated positions — a distinction that opens solution spaces that purely positional negotiation closes off. A practical example in a hospitality or retail context: two employees in conflict over shift preferences may both have the underlying interest of spending weekend time with family. Once the underlying interest is visible and acknowledged by both parties, multiple scheduling solutions become available that a binary argument about who has the right to a specific shift would never generate.

Structured feedback conversations as conflict prevention

Many workplace conflicts are the delayed and compounded product of accumulated unspoken frustrations that were never addressed in regular management conversations. Training managers to conduct regular structured one-to-one meetings — using frameworks such as the SBI model (Situation-Behavior-Impact) — gives employees a regular, normalized channel for raising concerns before they grow into resentments. Employees who have a reliable feedback channel are significantly less likely to let frustrations accumulate until they erupt as interpersonal conflict affecting the whole team.

When conflicts become legal matters in Belgium

Some workplace conflicts reach the threshold of formal legal proceedings under Belgian law. The Law of 4 August 1996 on psychological well-being at work creates specific obligations for employers when harassment or violence is alleged. Employees have the right to access a prevention advisor specialized in psychosocial risks, and the formal complaint procedure has defined steps that must be followed precisely. HR managers must be fully familiar with these procedures and ensure that formal psychosocial complaints are handled strictly according to the legally defined process, with complete documentation at every stage.

Practical tips for HR managers

• Address tensions early — intervene at the first observable sign of friction, not after the situation has escalated to open conflict or formal complaint
• Train all managers in active listening and basic de-escalation techniques as a standard component of their management development program
• Create a clear, genuinely accessible, and confidential process for employees to raise concerns before they crystallize into formal conflicts
• Document all formal conflict resolution conversations and agreed outcomes in writing, signed and dated by both parties
• Follow up at 30 days after resolution to verify that agreements are being honored and that working relationships have genuinely stabilized
• Track conflict frequency by team, shift, and manager to identify systemic scheduling or management issues driving recurring tensions across the organization

Frequently asked questions

What is the difference between a conflict and a formal grievance under Belgian labor law?

A conflict is an interpersonal disagreement that can typically be resolved through management intervention or mediation without triggering formally defined legal procedures. A formal grievance — or more specifically a psychosocial risk complaint under Belgian law — activates a defined legal process involving the prevention advisor, specific timelines, and documented formal procedures. Not every conflict becomes a grievance, but unresolved conflicts frequently escalate into formal proceedings that cost significantly more time, money, and management attention than early-stage mediation would have required.

How should HR respond when a conflict involves a manager and their direct report?

Power imbalances require particularly careful and deliberate management. Interview both parties separately and privately before any joint conversation, ensure the employee is clearly informed of their rights including the right to access the prevention advisor for psychosocial risks, and engage an independent mediator rather than attempting to resolve the conflict through the management hierarchy that itself contains the imbalance. The employee must never feel — through word or action — that raising the conflict puts their position, performance evaluation, or future opportunities within the organization at risk.

Can scheduling practices cause or worsen interpersonal conflict at work?

Yes, scheduling is one of the most common structural triggers of workplace conflict in shift-based environments across Belgium. Perceived unfairness in shift allocation, last-minute changes that disrupt personal plans without adequate notice, inconsistent application of scheduling rules between team members, and lack of transparency about how scheduling decisions are made all create ongoing resentment that accumulates and eventually manifests as interpersonal conflict. Transparent, digital scheduling systems that apply consistent rules to all employees and allow staff visibility into how decisions are made significantly reduce scheduling-related conflict at its structural source.

What early warning signs indicate a conflict is approaching the formal complaint stage?

Warning signs that a conflict is escalating beyond informal resolution include: requests from either party to change shift or team assignment to avoid contact with a specific colleague, reports of the conflict reaching HR through third parties not directly involved, changes in attendance patterns that coincide precisely with scheduled interactions with the other party, and explicit statements from either party that they are considering a formal complaint or consulting an external advisor. Any of these signals warrants immediate HR intervention at the structured mediation level, before the formal legal process is triggered with all its associated costs and obligations.
