Acknowledging that only examining the main effects of diversity may be limiting, the authors explore integrating van Knippenberg et al.'s (2004) categorization–elaboration model (CEM) of workgroup diversity as a linchpin in the relationship between empowering leadership and performance in age-diverse work groups. While prior research has focused almost exclusively on the impact of transformational leadership in diverse contexts, few studies have found the positive effects of transformational leadership to be diminished in certain age-diverse contexts. Consequently, the authors investigate whether empowering leadership may be a better approach in this context due to its emphasis on accommodating and participative behaviors.

Using survey data gathered from work group members across a wide array of industries (N = 214), the authors test for the moderating effects of empowering leadership on the relationship between age diversity and work group performance and its indirect relationship via information elaboration (while controlling for transformational leadership).

Empowering leadership positively moderated the direct relationship between age diversity and work group performance and the indirect relationship via information elaboration, whereas transformational leadership had the opposite effect. “Coaching” and “showing concern/interacting with the team” drove the positive effects of empowering leadership, and “personal recognition” and “intellectual stimulation” predicted the negative effects of transformational leadership.

This research offers insights into how managers can lead age-diverse work groups more effectively (i.e. by utilizing an empowering as opposed to a transformational leadership approach, with a particular emphasis on “coaching” and “showing concern/interacting with the team” behaviors).

The study identifies an “alternative” moderating contingency to the age diversity–performance relationship (empowering leadership).

The purpose of this paper is to introduce the concept of work group diversity dynamics as a novel approach for studying diverse work groups. The authors profile the dynamic processes within diverse work-groups and provide an overview of main objectives.

The paper draws on years of accumulated diversity research to cast a temporal and dynamic lens on the processes taking place within diverse work groups. After outlining the state of the art in work group diversity research, the definition, overall framework and profile of work group diversity dynamics is offered.

The paper argues that by adopting a temporal and dynamic perspective for studying diverse work groups, one can shift focus from the traditional perspective of “what is diversity” to “what happens within diverse work groups”. The paper disentangles the activities taking place within diverse work groups, defines the actual team processes and finally highlights how these processes might be affected by time and dynamism.

After almost 30 years of diversity research the mechanisms and processes through which diversity is translated into individual and organizational outcomes are not yet sufficiently understood and studied. This paper highlights a temporal and dynamic perspective for studying work group diversity, a view that is yet uncharted in diversity literature.

The purpose of this study was to explore the relation between diversity in work group members’ employment arrangements and the actual performance of the work groups.

A field study was conducted on 31 work groups in a public plant belonging to the industrial sector that constitute a unique data set. The 441 employees are contracted under four significantly different employment arrangements and are mixed together in heterogeneous work groups, but perform similar tasks.

The results indicated that the influence of employment arrangement diversity on work group performance is best represented as variation, and work arrangements diversity is positively correlated with improved work group performance.

The study design prevented assessment of employees’ opinions. Rather, the authors used objective type of employment arrangements as the basis for calculating diversity as separation. Using mean Euclidean distance as suggested by Harrison and Klein (2007), the authors arbitrarily set the distance between two different employment arrangements as one.

The research results help in the stages of recruiting, structuring and development and application of necessary work team. Formal emphasis of diversity in work arrangements improves performance.

To the authors’ knowledge, this is one of the first studies using unique data set analyzing real-life team diversity and performance in the public sector. The research highly contributes to organizational decision-making processes regarding the importance of incorporating non-standard work arrangements in organizations. Management’s implementation of formal diversity seems to alleviate the negative sides of diversity and increases its positive performance effects.

The purpose of this paper is to examine the role of enriched group work design and objective and perceived expertise diversity in interdisciplinary research groups with a focus on two critical group processes: task conflict and idea sharing.

Survey data were collected from 148 researchers and their advisors in 29 research labs at two doctorate-granting universities. The study tested the hypothesized model using hierarchical ordinary least squares regression and hierarchical linear modeling.

Results showed that objective and perceived (salient) expertise diversity jointly influenced task conflict. In addition, whether task conflict had a positive or negative impact on idea sharing depended on group work design enrichment and expertise diversity salience. Idea sharing improved group outcomes over and above the effects of task conflict.

Although this study could not test the causal relationships owing to a cross-sectional nature of data, it provides theoretical implications for the group work design, diversity and conflict literature.

Group work design represents an important tool for stimulating idea sharing in research groups. The findings suggest that managers should consider and manage the level of expertise diversity salience and the level of task conflict to increase the effectiveness of group work design.

The study provides insights on when task conflict may help creative groups. Work design and diversity salience represent important contextual features. The paper also examines both the objective and perceived diversity and disentangles task conflict and idea sharing.

This study seeks to determine factors that encourage post‐meeting work activity in a software development group by assessing attendee diversity (functional, staffing and tenure), meeting size, and meeting history.

One year's worth of meeting data from a software development group in a US‐based financial services company were collected and analyzed. A binary logistic regression analysis was utilized to determine the impact of diversity, meeting size, and meeting history on the likelihood of post‐meeting work activity.

Tenure diversity and meeting history for each meeting event significantly contribute to the likelihood of post‐meeting work activity.

A lack of variance in the data does not allow for the examination of staffing diversity. Further, generalizability of findings is limited since data come entirely from one organization. Findings suggest that meeting characteristics, specifically tenure diversity and meeting history, can improve the likelihood of post‐meeting work activity occurring.

Findings illustrate that management can leverage tenure diversity and meeting history within a software development group to encourage post‐meeting work activity.

All organizations employ meetings, and research that clarifies how to extract maximum value from meeting events is critical. This study provides a first step in uncovering specific meeting characteristics which are most likely to impact post‐meeting work activity.

The purpose of this paper is to help organizations capitalize on the potential advantages of age diversity by offering insight into two new moderators in the age diversity, work group performance relationship – status congruity and cognition-based trust.

The authors surveyed 197 employees and 56 supervisors across 59 work groups to test for the moderating effects of status congruity and cognition-based trust on the age diversity, work group performance relationship.

The results demonstrated, on the one hand, that under conditions of status congruity (i.e. when there were high levels of perceived status legitimacy and veridicality) and/or when perceptions of cognition-based trust were high within the group, the relationship between age diversity and work group performance was positive. On the other hand, under conditions of status incongruity and/or low levels of cognition-based trust, this relationship was negative.

The findings contribute to the literature by being the first to provide empirical evidence for the theorized effects of status on the performance of age-diverse work groups and also by demonstrating the effects of cognition-based trust in a new context – age-diverse work groups.

Arising from the study’s findings are several strategies, which are expected to help organizations enhance perceptions of status congruity and/or trust and ultimately the performance of their age-diverse work groups.

The paper is the first to empirically demonstrate the moderating effects of status congruity and cognition-based trust on the age diversity, work group performance relationship. The study also establishes important distinctions between the effects of objective status differences vs status perceptions.

In order to manage strategic demographic change in economic and labor markets, a common human resource (HR) change strategy is to increase the diversity of the workforce through hiring over time. This study examined department level consensus and valence regarding an organizational HR strategy to shift demography toward greater diversity in race and sex composition over an eight‐year period. Though the organization had experienced significant change in organizational demography: an increase in the overall representation of white women (36 percent) and minorities (41 percent) over time; work group members in units with the greatest change did not necessarily agree nor hold positive perceptions regarding these HR changes. The results show that HR strategies that focus on structural change without working to develop supportive group norms and positive climate may be inadequate change strategies.

The purpose of this article is to empirically examine the relationship between managers' emotional exhaustion and the ethnic diversity, workload requirements, and friendship ties within their work-groups.

The research employs a full-network sample of all managers from an indigenously owned ethnically diverse IT firm located in the Caribbean island nation of Trinidad and Tobago. Using a social network design within a regression model, the relationship between managerial power and operational workload and the burnout dimension of emotional exhaustion is initially examined as a baseline model. Work-group ethnicity and friendship ties are then examined as moderators to this relationship. The authors then examine the role of work-group ethnicity and friendship ties as a buffer mechanism using an efficient frontier analysis where managers act as decision-making units.

The study indicates that ethnic diversity acts more as a “negative moderator” to emotional exhaustion, while friendship ties act as both a “positive moderator” and “buffer” to work-related emotional exhaustion.

This is one of the few empirical studies that has examined the issues of ethnic diversity and burnout using social network and efficient frontier methodologies. This is also one of the first empirical studies to investigate these issues using an in-depth, full-sample case study of actual, real-work network relationships.

The purpose of this paper is to extend current discussion on the drivers of innovative work behavior (IWB) by exploring how individual perceived diversities (visible dissimilarity and cognitive group diversity) and climates (team/clan and innovative/entrepreneurial) impact IWB.

Data had been collected from a cross-national study of working professionals (n = 584) from five different cultural contexts.

Findings of this study indicated that cognitive group diversity mediated the negative relationship between visible dissimilarity and IWB. Further, both innovative/entrepreneurial and team/clan climates moderated the relationship between visible dissimilarity and cognitive group diversity. Such a moderation effect reduced the negative effect that visible dissimilarity had on IWB.

A cross-sectional single-source data set.

From a managerial perspective, climates (team/clan and innovative/entrepreneurial) are central for IWB in the diverse (visible and cognitive) working environment. Thus, organizations should pay attention to create a climate (team/clan or/and innovative/entrepreneurial) that reduces the negative impact of perceived diversity in the working environment while supporting IWB.

This study is the first of its kind that is based on social categorization theory, empirically examining how different types of diversity (visible dissimilarity and cognitive group diversity) simultaneously reduce individuals’ IWB. Furthermore, this paper provides insights that climates (team/clan and innovative/entrepreneurial) are crucial for IWB in the diverse working environment.

Successful developers need to manage a large number of cooperation partners and find innovative solutions for specific tasks, as each real estate project is somehow unique. Thus, the question arises as to whether intelligent group formation for real estate development calls for more or rather less diverse project groups.

This paper aims to test the impact of group diversity on overall group performance with a unique data set. The authors collected the results of 150 project assignments from real estate executive education students at the IREBS Real Estate Academy from 2010 until 2016.

The authors find that group results were impacted positively for groups with disparity in work experience and ability. Differences in sex and age did not yield any measurable impact, neither positive nor negative.

To the best of the authors’ knowledge, this is the first time that the relationship between work group diversity and group performance was tested for real estate educational projects. The authors believe that the results are highly relevant for all university work, for which teams have to cooperate on complex rather than basic assignments and problems. Moreover, they are the first to develop a framework that combines diversity theories with a clear distinction between three diversity concepts.
