In recent decades, the number of people living with one or more chronic diseases has increased dramatically, affecting all sectors of society, particularly the labour market. Such an increase of people with chronic diseases combined with the aging of working population affects income levels and job opportunities, careers, social inclusion and working conditions. Both legislation and company regulations should take into account the difficulties that workers experiencing chronic diseases may face in order to be able to formulate innovative and person-centred responses to effectively manage this workforce while simultaneously ensuring employee wellbeing and continued employer productivity. The European Joint Action "CHRODIS PLUS: Implementing good practices for Chronic Diseases" supports European Union Member States in the implementation of new and innovative policies and practices for health promotion, diseases prevention and for promoting participation of people with chronic diseases in labour market. Therefore, a has been developed and its aim is to improve work access and participation of people with chronic diseases and to support employers in implementing health promotion and chronic disease prevention activities in the workplace. The Toolbox consists of two independent instruments: the Training tool for managers and the Toolkit for workplaces that have been tested in different medium and large companies and working sectors in several European countries.
