One of the most important consequences of the development of remote work is that the company ceases to exist as the only place to work. By multiplying work in different places, remote working complicates the implementation and the respect of the legal framework for safety and health at work. Cross-border telework follows the same upward trend as other telework . But, in a context of cross-border, the telework gains in complexity. In this context, the study aims to compare the French and Spanish frameworks for remote working, particularly in terms of occupational safety and health. This comparison highlights the different approach between the French and Spanish frameworks.
