Taking over someone's work without hurting their feelings

Today: taking over someone's work without hurting their feelings. Aung Zin Phyo, from Myanmar, works for a firm that makes architectural 3DCG images. These images are used in various types of presentations. He joined this company last year. He supervises his colleagues who work in Vietnam. Since both parties are communicating in Japanese rather than their native languages, he aims to take care with how he expresses himself. He'll tackle a roleplay challenge, in which he must help out a coworker who is struggling with their workload.
