Purpose Based on the social exchange theory and the reactance theory, the purpose of this paper is to investigate the effects of workplace abuse from two sources. The study explores the linkage between abusive supervision and co-worker abuse on the targeted employee’s organizational commitment, organizational citizenship behavior and intention to quit as mediated by procedural justice. Furthermore, this study extends understanding workplace abuse consequences by investigating its effects on organizational citizenship behavior directed to individuals and organizational citizenship behavior directed to the organization. Design/methodology/approach To test the proposed hypotheses, a cross-sectional research design was used. The sample comprised 500 employees working in various private and public sector organizations in the Republic of Trinidad and Tobago. Using a split-sample approach, mediation analyses were performed on the test and validation samples. Findings The research results showed that procedural justice mediated the relationship between abusive supervision and affective and normative commitment, organizational citizenship behavior directed to individuals and intention to quit. Procedural justice was found to mediate the relationship between co-worker abuse and affective and normative commitment, and intention to quit. Originality/value This study extends previous academic studies on workplace abuse by comparing the effects of abusive supervision and the lesser researched source of co-worker abuse on the targeted employee’s organizational commitment, organizational citizenship behavior and intention to quit. It also reports on the effects of each source on an employee’s organizational citizenship behavior directed to individuals and organizational citizenship behavior directed to the organization, as there is limited empirical research within the workplace abuse literate on these two dimensions.

PurposeAs group work is becoming more common in the classroom, teamwork as an andragogical tool continues to be problematic for students in management programs. The purpose of this paper is to determine how university students perceive teamwork and to identify teamwork problems along with potential solutions.Design/methodology/approachA triangulation mixed-methods approach was used. In study 1, qualitative data were gathered from a focus group comprising nine students. In study 2, quantitative data were gathered from an online survey completed by 127 students.FindingsThe data were analyzed using content analysis and ordinary least squares regression. The results indicated that free-rider experiences and peer evaluation are two key areas in determining dissatisfaction with teamwork. Teamwork challenges may be addressed via knowledgeable team leaders who balance task and relationship styles, equitable workloads, smaller team sizes, anonymous peer evaluations and the effective use of technology.Practical implicationsThe findings are valuable to educators at tertiary-level institutions who utilize teamwork as an andragogical tool.Originality/valueThis study was designed to deepen understanding of university students' dissatisfaction with teamwork in Trinidad and Tobago and provide andragogical improvements that can be implemented to enhance the students' teamwork experience.

BACKGROUND: Research on workplace sexual harassment has focused largely on its direct antecedents and consequences. In contrast, few studies unravel mechanisms through which sexual harassment is related to organizational outcomes. OBJECTIVE: Following affective events theory, the purpose of this paper is to investigate mental health as a mechanism in the relationship between sexual harassment and organizational commitment. METHODS: Quantitative data were collected using a survey design for which 249 employees responded. RESULTS: Structural equation modeling showed that the mediation model was partially supported for the overall sample because mental health was a partial and not full mediator. However, post-hoc analysis revealed that the mediation model was suited to men, but not women. CONCLUSIONS: This study contributes to sexual harassment research by (a) investigating a novel mechanism in the sexual harassment to organizational commitment relationship and (b) highlighting the importance of gender differences when attempting to unravel the sexual harassment causal chain. Implications for organizations regarding the development of sexual harassment policies, complaint procedures, and training are explained.
