This study explores how Generation Z constructs work values and meaning in modern organizations shaped by digitalization and social transformation. Using a qualitative phenomenological approach under a social constructivist paradigm, the research investigates the lived experiences of young professionals in the digital, creative, and startup sectors. Data were collected through in-depth interviews and non-participant observation and analyzed using thematic analysis (Braun & Clarke, 2006; Moustakas, 1994). Findings show that Generation Z defines work through three interrelated dimensions: (1) intrinsic motivation grounded in personal purpose and self-expression, (2) redefined productivity emphasizing creativity and emotional balance rather than quantitative output, and (3) job satisfaction derived from inclusive culture and adaptive leadership. These results support Self-Determination Theory (Deci & Ryan, 2000) and Social Constructionism (Berger & Luckmann, 1966), showing that work meaning is socially constructed rather than objectively given. Overall, the study concludes that for Generation Z, work represents not merely economic activity but a medium for identity, contribution, and personal growth, urging organizations to embrace meaning-centered and value-driven leadership to enhance engagement and fulfillment.

This research aims to compare modern international trade theories from conventional and Islamic economic perspectives. The technique used is a literature review through the analysis of sources from journals, books, and related research. The findings of this research indicate that international trade theory in the conventional perspective prioritizes efficiency, specialization, and increased profits through free market mechanisms, such as the theory of absolute advantage, comparative advantage, the H-O factor proportion, and the theory of large-scale economies. However, this approach often overlooks moral aspects, distributional justice, and the risk of exploitation. On the other hand, the Islamic perspective views trade as a muamalah activity based on justice, trustworthiness (amanah), the prohibition of riba (interest), gharar (uncertainty), and maisir (gambling), as well as the objectives of maqasid sharia (the objectives of Sharia). Both views recognize the importance of trade for economic growth but differ in their basic values and ethics. In today's era of globalization and digitalization, the importance of integrating Islamic values into international trade is increasingly understood. This aims to build a more just, sustainable, and inclusive trading system. This research emphasizes the need to apply Sharia principles in contemporary trade practices, including the application of Islamic financial instruments, the development of halal e-commerce platforms, and ethical oversight within global supply chains. In this way, it is hoped that international trade can provide broader benefits to all of humanity, in accordance with the principles of justice and welfare in Islam. The interconnectedness of both approaches in the digital context demonstrates the need to unite Islamic moral values with changes in today's global trade.
