The COVID-19 pandemic has altered work environments globally, prompting significant changes in work-life balance and employee wellbeing. The aim of this thesis was to investigate the effects and changes that the COVID-19 pandemic has brought about in the work-life balance and wellbeing of employees during the crisis and the results of those changes afterwards. The literature review proved that the pandemic accelerated the adoption of flexible work plans, leading to a shift towards hybrid work models. While offering flexibility, working from home create difficulties in managing work-life boundaries. The shift to hybrid work has implications for employee wellbeing, with factors such as organizational support and digital infrastructure playing crucial roles in shaping employee experiences and outcomes. At the same time, longitudinal studies indicate that ongoing evaluation and refinement of remote work policies are essential for sustaining positive outcomes in organizations, emphasizing the need for adaptable strategies. Moving forward, organizations and policymakers must continue to adjust and innovate to meet the evolving needs of employees while ensuring sustainable work-life balance and promoting overall wellbeing. By embracing flexibility, leveraging technological advancements, and prioritizing employee support, organizations can cultivate a workforce capable of maintaining viable work-life balance while thriving in dynamic environments.
