Antidepressant adherence and breast cancer recurrence risk in women with major depressive disorder: a retrospective cohort.

Workplace Mental health and well-being are essential to employees (). It can be influenced by the work environment, characterized by inclusion, respect, equity, and a supportive culture. Mental Health is defined by the World Health Organization () as “a state of well-being in which an individual realizes his or her abilities, can cope with the normal stresses of life, can work productively and can contribute to his or her community.” Employees who experience better mental health and well-being within the workplace, shaped by psychosocial working conditions such as job demands, organizational support, and work environment, are better able to perform effectively, manage work-related challenges, and maintain productivity (). In contrast, poor workplace mental health and reduced well-being, often arising from adverse work conditions, are associated with lower job satisfaction, impaired performance, increased absenteeism, and a heightened risk of exhaustion and burnout (). According to a recent global survey conducted across 11 countries involving 4,000 employees, managers, and business leaders, 63% of employees believe their managers or employers have ignored their voices (). refers to employees’ perceptions that they are valued, noticed, and that their contributions are important within the organization (). One key manifestation of employee mattering is the extent to which employees feel their are heard and considered in workplace decisions, signalling recognition and respect from leadership and peers. When employees experience low levels of mattering, they are more likely to report disengagement, reduced well-being, and diminished motivation, all of which can negatively affect organizational functioning (). Despite its relevance to organizational health and employee success, research examining employee mattering in workplace contexts remains limited, highlighting the need for further investigation (; ). Workplace mental health is a significant concern for employers, and these findings highlight the need for better support and attention to employees’ voices and well-being. Workplace mental health has increasingly been recognized as a critical determinant of employee well-being and organizational functioning. To guide organizations in promoting psychologically healthy work environments, the U.S. Surgeon General outlined five core themes for workplace mental health, including protection from harm, connection and community, work–life harmony, organizational trust, and mattering at work (). Among these themes, —employees’ perceptions that they are valued, recognized, and that their contributions are meaningful—has received comparatively less empirical attention, despite its central role in shaping engagement, motivation, and well-being. Accordingly, the present study focuses specifically on mattering at work to address this gap and to better understand its implications for workplace mental health.
