There is an urgent need for mental healthcare in the workplace though little has been done so far to address that. Many tragic incidents such as workplace suicide and death due to ‘workplace bullying’, ‘violence’ and ‘overwork’ have happened in South Korea and Japan. The unemployment rate of workers suffering from mental health problems is also increasing, which aggravates the risk of serious economic impacts for an aging population. Therefore, it is crucial to establish a mental health management system at the workplace level. This chapter presents a model based on the use of smart technologies for mental healthcare services to enhance the ergonomics and quality of working conditions at the workplace, and to help create a mentally healthy workplace. With the rapid development of SmartMentalTech, an innovative shift with new ways of delivering mental healthcare services is taking place changing the way service users, employers, and system designers use technology to deliver mental healthcare at the workplace. The objective of this chapter is to suggest an ergonomic platform where viable applications related to psychological challenges at the workplace are provided by service users, developers, practitioners, decision makers, and policymakers. The approach of Occupational Health Psychology (OHP) emphasizes on the significance of workplace design, management and psychosocial risk mitigation. There are differences across service users; therefore, the challenges facing the managers of mental healthcare services at the workplace are daunting. Currently 12 types of developed SmartMentalTech can be used for personalized care. This chapter provides a comprehensive account on how to set up and to manage mental healthcare delivery in order to minimize workplace mental health problems and the social stigma of mental health issues by establishing a new comprehensive mental healthcare stepped-care model (CMHSCM) system for service users' satisfaction and healthy intelligent workplace in a timely and economically responsive manner.
