Regulatory aspects
For supervised entities in the financial sector, further requirements may apply in relation to remote work. E.g., the CSSF in Luxembourg has recently issued a circular (21/769) about governance and security requirements for supervised entities to perform tasks or activities through telework (post pandemic).
Employment law
The protective rules of local employment law may apply in a cross-border environment, and in some cases, these rules may interfere with the legal provisions in force in the country of employment (such as minimum wage, legal working hours, duration of paid annual leave, public holidays, termination, etc). If an employee predominately works from another country (e.g., country of residence), the local legislation should apply.
