The aim of this research is to measure the mediation effect from organisational justice in the relationship between organisational ambidexterity and irritation. The measurements were included the aspects of organisational ambidexterity, which are exploitation and exploration, the aspects of irritation, which are emotional and cognitive irritation, and the aspects of organisational justice, which are distributional justice, interactional justice and procedural justice. There were full mediation effects of distributional justice in the relationship between exploitation with irritation and distributional justice with cognitive irritation. There were 26 foreign doctors as respondents in this research. This research measured an indirect mediation effect with the SPSS program from Andy F. Hayes. This research revealed that the hospitals implemented exploitation and the highest association was between distributional justice and cognitive irritation.
