Strategic priorities The Platform guides its work to tackle undeclared work according to 3 strategic priorities: cooperation and joint action mutual learning increasing knowledge Each strategic priority and its activities are interlinked and reinforce each other. Following the setting up of the European Labour Authority in 2019 (ELA), the Platform will be integrated into ELA as a permanent working group. Cooperation and joint action Platform members and observers are part of a unique EU-wide network where they can benefit from cooperation and joint actions. These include joint inspections and campaigns, which are tailored to meet local needs. Capacity-building activities, which include staff learning visits and mutual assistance projects, promote self-reflection, practical support from peers and can help bring about new policy approaches. Mutual learning The Platform focuses on learning from successful approaches, tried and tested in other European countries. Mutual learning activities through workshops and seminars help members and observers exchange information and improve how they prevent and tackle undeclared work. Outputs from these activities including learning resource papers and executive summaries can be found in the virtual library. Increasing knowledge Studies, surveys and reports on relevant and pertinent topics, which encourage informed policy-making and structural reform, are published by the Platform.
