Study of the Mediating Effect of Social Support and Interpersonal Conflicts in the Relationship between Work Overload and Work-Life Conflict. International Journal on Working Conditions, 27, 20-38.2182-9535http://hdl.handle.net/10400.26/52058In today's dynamic organizational landscape, constant changes have heightened pressure on businesses, exposing workers to a multitude of psychosocial risk factors that can detrimentally affect their professional and personal well-being. Among these factors, work overload has emerged as a significant concern, driven by the competitive demands placed on organizations. This study investigates the role of social factors within the organizational context as potential buffers or amplifiers of the effects of work overload, specifically focusing on social support from peers and levels of interpersonal conflict. Our sample comprises 203 workers, predominantly women (81.8%), with an average age of 40.05 years, representing diverse sectors. Findings reveal that work overload contributes to increased work-life conflict levels. Social support acts as a protective factor in this relationship, and interpersonal conflicts exacerbate this relationship. These insights hold theoretical and practical significance, offering organizations guidance on leveraging the social climate to mitigate the adverse effects of stressors like work overload.engWork OverloadWork-life ConflictPeer Social SupportInterpersonal Conflictjournal articlehttps://doi.org/10.25762/54v4-h980
