Social security and health
When you hire staff, be aware of EU rules on workers' social security contributions. A worker can only be subject to only one country's social security laws at a time, usually the laws of the country where they work, as an employee or self-employed.
Ensure that your employees work in a safe and healthy working environment. As an employer, you must follow EU-rules on risk assessment and management, to make sure you minimise the risk of accidents and prevent dangerous situations.
