Employees are increasingly being deployed outside of normal employment contractual frameworks, both at home and abroad. Examples include temporary work, but also the temporary posting of employees in subsidiaries or sister companies. This book provides a practical guide through the corresponding complex legal issues. The book deals with the questions of individual and collective labour law, the drafting of contracts, international labour law, employee transfer law, social security law and tax legislation. A wealth of practical information, overviews and templates offer valuable assistance to HR managers and legal advisers in the preparation, implementation and completion of these deployments.
