DIGITAL FATIGUE AND PROFESSIONAL BURNOUT AS MODERN THREATS TO ENTERPRISE PERSONNEL SECURITY UNDER DIGITALIZATION

Abstract

The article substantiates digital fatigue and occupational burnout as threats to personnel security amid digitalization’s. It argues that ICT, hybrid work, digital platforms and online interaction enhance productivity and flexibility, but also generate new psychosocial and human-resource risks. Digital fatigue is defined as cognitive, emotional and physical exhaustion caused by excessive use of devices, information overload, multitasking, availability and blurred boundaries between work and private life. Its symptoms include eye strain, mental exhaustion, sleep disorders, reduced concentration, irritability, lower motivation and poorer communication. The study emphasises that accumulated digital fatigue may become a prerequisite for occupational burnout, understood as a syndrome caused by unmanaged workplace stress. From the perspective of personnel security, both phenomena reduce productivity, increase errors, weaken discipline, decrease engagement, intensify turnover risks and undermine organizational resilience. Special attention is paid to employees’ vulnerability to cyber threats and manipulative digital influences, including phishing, vishing, ransomware, spyware, cyberbullying, trolling, hate speech and doxing. The article proves that the consequences of these phenomena go beyond individual well-being and transform into organizational, informational, reputational and economic risks. As a methodological basis for prevention, it proposes adapting ISO 45003:2021, which provides guidance for managing psychosocial risks at work. Key managerial measures include support policies, assessment of employees’ needs, regulation of digital workload, role clarity, autonomy, organizational justice, recognition, transparent communication, digital and cyber hygiene training, psychological support and effectiveness monitoring. Their implementation enables enterprises to minimize psychosocial risks, preserve human capital, strengthen personnel reliability and integrate psychological well-being into personnel security management.
