This article discusses interdisciplinary approaches to help students overcome communication barriers by integrating performing arts in Business Communication courses. Companies emphasize a workforce with solid soft skills to succeed. International Business employs English; thus, practical communication skills in English provide access to jobs in international scenarios. However, in Puerto Rico, second-language speakers of English feel intimidated when speaking it. The emotional barriers students endure while developing intercultural and communication skills in English is a topic worth researching. Performing arts provide strategies to raise body awareness and increase self-confidence. These elements will lead to a confident and effective communicator.

This research examines the role of idiomatic expressions (IEs) in international business (IB) communication and non-native speakers’ (NNEs’) English proficiency. It investigates how IE affect IB communication’s effectiveness and whether IEs should be taught to NNE. We collected feedback from academics who confirmed the importance of IE and relevant business idioms from professional websites. We also assessed IE usage benefits for different cohorts working in IB settings. The results indicate that IE can enhance communication efficiency, cross-cultural social skills, monetary rewards, and satisfaction in IB. The findings support the need for teaching IE to NNE and justify inclusion in curricula.
