This report explores the opportunities open to employees in workplaces across Europe to participate in decision-making, either in the context of their job or in relation to wider organisational issues affecting their work. Employee involvement is a key component of work organisation, relating to other dimensions such as physical working conditions and work intensity. Two dimensions of employee involvement are covered: task discretion – or the influence that employees can exercise over their immediate work tasks – and organisational participation – or the influence that employees have over work organisation. While in the EU27 as a whole there are limited opportunities for employees to participate in decision-making, the findings point to the clear benefits for employees in working in organisations that give greater scope for their involvement. Crucially, employee involvement has been shown to have a positive effect on employee motivation and psychological wellbeing, critical elements in fostering enhanced work performance and company productivity. An executive summary is also available.
