The European agency for safety and health at work (EU-OSHA) welcomes its network partners and high-level European and national representatives to a celebration of 25 years of working together for a safe and healthy Europe. Two panel sessions will offer participants the opportunity to reflect on and share their experiences of occupational safety and health (OSH) over the past 25 years, and discuss future challenges. The event is a celebration of the achievements of the European network of OSH players that EU-OSHA has built over the years. It highlights the contributions that EU-OSHA, its national focal point network and other partners have made, and will continue to make, to creating safe and healthy workplaces across Europe.
