Impact of Workplace Ergonomics on Physiological Stress in Tech Industry Employees

Thesis Abstract

In the rapidly expanding technology sector, employee productivity and well-being are increasingly influenced by workplace environmental factors, particularly ergonomics, which directly affect physiological stress levels among tech industry employees. Despite widespread acknowledgment of ergonomic design's importance, empirical evidence linking ergonomic interventions to physiological stress mitigation remains limited, especially within the context of remote and hybrid work environments prevalent in the sector. This study aims to investigate the impact of workplace ergonomics on physiological stress among employees of a major technology firm, with specific objectives to assess ergonomic risk factors, measure physiological stress markers, and evaluate the effectiveness of ergonomic interventions. The research adopts a cross-sectional correlational design, grounded in the transactional model of stress and the ergonomic fit theory, to explore associations between ergonomic conditions and physiological stress indicators. The study population comprises 250 full-time software developers and IT support staff employed at a leading tech company in the metropolitan area. A stratified random sampling technique ensures representative inclusion across various departments and experience levels. Data collection employs a mixed-methods approach quantitative data are gathered through structured questionnaires, direct physiological measurements, including salivary cortisol levels and heart rate variability (HRV), and ergonomic assessment checklists. The questionnaires include the Nordic Musculoskeletal Questionnaire to evaluate ergonomic risk exposures, while physiological data are collected using portable, validated devices. Reliability and validity of the instruments are established through pilot testing and Cronbach’s alpha coefficients exceeding 0.80. Data analysis involves descriptive statistics to profile ergonomic conditions and stress levels, followed by inferential analysis using multiple regression techniques to determine the relationship between ergonomic factors and physiological stress markers. ANOVA tests are employed to compare stress levels across different ergonomic risk categories, and correlation analysis examines the strength of associations. The study also incorporates thematic analysis of qualitative feedback from participant interviews regarding ergonomic perceptions and stress experiences. By integrating these methods, the research aims to elucidate the extent to which ergonomic design influences physiological stress responses. The anticipated findings suggest a significant negative relationship between ergonomic adequacy and physiological stress markers, indicating that improved ergonomic conditions are associated with reduced cortisol levels and enhanced HRV. These results are expected to demonstrate that ergonomic interventions can effectively mitigate work-related physiological stress, thereby contributing to better health outcomes and enhanced productivity among tech employees. The findings will provide empirical evidence supporting targeted ergonomic modifications within the workplace as a strategic approach to reducing stress-related health risks. This research contributes to the existing body of knowledge by empirically establishing the physiological benefits of ergonomic interventions in a high-stress work environment, filling a notable gap in sector-specific occupational health literature. It offers a validated model that links ergonomic design to physiological stress reduction, which can inform organizational policies and ergonomic standards in the tech industry. The study highlights the importance of integrating ergonomic assessments into occupational health strategies and emphasizes the role of workplace design in promoting employee well-being. In conclusion, the study underscores the critical role of workplace ergonomics in managing physiological stress among tech industry employees. It recommends implementing comprehensive ergonomic programs, regular ergonomic assessments, and employee training to foster healthier work environments. Future research should explore longitudinal impacts of ergonomic interventions and extend investigations to remote work settings, thereby broadening understanding and facilitating the development of sustainable ergonomic practices tailored to evolving work dynamics.
