To become one, a written agreement must be established between the employee and the employer, if you are an employee. The frequency of remote work must be mentioned and your employer must provide you with the necessary equipment and technical support. Your employer must also contribute to the operating costs (provision of internet connection, computer or telephone, possible participation in heating or electricity costs, etc.). However, if you are a freelancer, there is no obligation to stay in a fixed country. It is therefore easier to become a world worker by being a freelancer.
