Finnish workplaces are becoming increasingly multicultural and more dependent on international talent. However, onboarding, communication, and leadership practices are often based on the Finnish language and an assumption of familiarity with Finnish working culture. This can lead to misunderstandings, inefficiency, and safety-related challenges in everyday work. The aim of this project is to develop a modern, multilingual onboarding and training solution that lowers language barriers and clearly explains the norms, expectations, and underlying logic of Finnish working life in a practical way. The solution takes cultural differences in communication and leadership into account and supports leadership practices that work in multicultural teams. The project seeks to improve multilingual and cross-cultural communication, reduce misunderstandings affecting work efficiency and safety, and strengthen trust within work communities so that employees feel safe to raise concerns and speak openly. Key question:What does an effective, multilingual onboarding and leadership solution for multicultural workplaces in Finland look like?
