The COVID-19 pandemic accelerated the adoption of Flexible Work Arrangements (FWA) globally. Understanding the impact of postpandemic FWA policies on employee Work-life Balance (WLB) outcomes is crucial as organizations redefine work models for the future. This research examined the impact of post-pandemic FWA policies on the WLB of employees, focusing specifically on 128 professionals at multinational corporations (MNCs) in Delhi-NCR, India. Adopting a quantitative methodology, the study analyzed the effects of FWA provisions on facets of WLB using a Survey Questionnaire. The multidimensional WLB construct comprised aspects like Nature of Work, Workload, Compensation, Organizational Support, and Personal Life. The objective was to assess if FWA positively affected overall WLB, while also testing the moderating effects of demographics. Hypotheses were tested using ANCOVA and Regression Modelling. The findings revealed that FWA positively influenced overall WLB and specific dimensions, affirming benefits of autonomy. However, interactions with demographics emphasized customizing FWA policies to needs across Career Stages, Gender, and Family Roles. The implications guide organizations in sustaining healthy, empowered workforces through tailored, empathetic FWAs aligned to the evolving responsibilities. The study provides data-backed insights and actionable guidance regarding the transitioning work landscape in the new normal. Further research can be built upon the findings to optimize flexible work strategies as workplace transformations continue apace in the post-COVID era.
