**Labour and social security inspectors from EU Member States** gathered in **Madrid** in a workshop on concerted and joint inspections on **19th - 21st October**.

For the first time inspectors from MS had the opportunity to meet in person to exchange their experiences on the most common **cross-border irregularities**, discuss practical cases and ways how to tackle irregularities **by carrying out cross-border inspections**. Discussions were supported by interventions of several EU Labour Mobility experts in the fields of **road transport**, **construction** and **seasonal work**. National experts who took part in concerted and joint inspections over the past two years could share their insights.

Cross-border infringements and irregularities faced by national authorities require an efficient collaborative transnational approach: this workshop represents a further step for **labour and social security inspectors** **who regularly engage in concerted and joint inspections** to build their professional relationships and **promote knowledge sharing**.
