Subtle workplace exclusion is often difficult to recognize. A colleague is not included in informal conversations, receives little response to ideas, or is repeatedly left out of important moments. Because these situations are ambiguous, employees often first doubt their own interpretation.

The straw that broke the camel’s back

In the publication The straw that broke the camel’s back: How attributions and a mental tipping point shape lived reactions to subtle workplace exclusion, Jamie Breukel, Sanne Nijs, Hans van Dijk, Marloes van Engen, Marijn Krol, and Stefanie Duijndam examine how employees experience subtle exclusion and how their reactions change over time. The publication appeared in Academy of Management Discoveries.

The researchers are affiliated with Tilburg University, TIAS School for Business and Society, and Radboud University. Hans van Dijk is Full Professor in Leading Inclusion at TIAS and conducts research on diversity, inclusion, and social inequality in the workplace and society.

From doubt to tipping point

The researchers interviewed employees about their personal experiences with subtle exclusion at work. The interviews show that employees are often not immediately sure what is happening. They wonder whether they are interpreting the situation correctly, whether they have done something wrong themselves, or whether others’ behavior is intentional or unintentional.

The researchers call this uncertainty attributional ambiguity: a lack of clarity about the cause of what someone is experiencing. In this phase, employees often first try to repair the relationship. They seek more contact, adapt their behavior, or try even harder to belong.

When these efforts do not work or become too draining, their response may change. Employees may withdraw, take less initiative, or become more silent within the organization. Eventually, a mental tipping point may occur: the moment when doubt disappears and someone starts to see the exclusion as a clear pattern.

The SWEAR model

Based on the interviews, the researchers developed the Subtle Workplace Exclusion Attribution and Reaction model, or SWEAR model. This model shows how interpretations of and reactions to subtle exclusion can develop over time.

The model describes a shift from attributional ambiguity to attributional clarity. Once employees more clearly see that the cause of the exclusion lies outside themselves, their response often changes as well. Some employees speak up to restore justice. Others see no room or effect in doing so and instead distance themselves further.

According to the study, three triggers can contribute to this tipping point: an accumulation of exclusion incidents, comparison with how others are treated, and external signals, for example from a colleague, manager, confidential advisor, or external source.

What leaders can learn from this

For organizations and leaders, this is an important insight. Inclusion is not only about policy, but also about everyday behavior, team dynamics, and taking signals seriously that may seem small at first glance.

This calls for leaders who are aware of what is happening beneath the surface. Leaders can help by recognizing patterns in teams, taking employees’ experiences seriously, and creating space to discuss exclusion. Precisely because subtle exclusion is often ambiguous, support from a manager, HR professional, or colleague can help people make sense of their experiences and gain clarity sooner.

In the leadership and management programs at TIAS, professionals develop their leadership in relation to themselves, their team, their organization, and the broader societal context. The programs help leaders act more consciously in complex situations, increase their impact, and create space for sustainable change.

Advanced Leadership and Management Program

One example is the Advanced Leadership and Management Program. Hans van Dijk is Academic Director of this program. In the program, experienced leaders work on their development at a personal, organizational, and strategic level. Topics such as inclusive leadership, team dynamics, reflection, and dealing with complex leadership challenges are addressed in the program and connect with the insights from his research.
