The purpose of this study is to analyze workload of elementary school teachers in Korea. Especially, we focused on emotions teachers feel when they are working. Semi-structured interview with elementary school teachers was used to achieve the purpose. First, elementary school teachers are performing a lot of tasks such as planning and preparing for instruction, the instruction and learning related activities, student guidance and management support, classroom instruction and so on in school. The features of their tasks are simultaneous and closely connected with many students. Second, time according to each work is unclear. Below are emotions teachers feel when they are working. Teachers feel anxiety and sorry due to the lack of time to prepare for instruction, guide and support their students. Teachers experience sense of shame because they can not act according to their conviction over the forced policy. Also, they are confused with a lot of administrative duties. In this situation, teachers endure negative emotions such as unhappiness, stress, sense of guilt, confusion, helplessness, fear, and frustration. Based on the results, it is recommended: The government should listen carefully and address the actual needs and emotions of teachers rather than giving out general policies. Simultaneously, teachers should retain the attitude of trying to advance their teaching professionalism and teachers culture.
