More than ever, companies are compelled by the ongoing financial and economic crisis to reassess their financial situation, their corporate and operational structure, as well as future economic opportunities and risks. However, even outside of crisis situations, a market economy is unthinkable without the freedom of companies to respond to external factors and to continuously adapt to changing market conditions. Only the constant search for the optimal corporate and operational structure and its implementation can ensure the increased flexibility demanded of companies in global markets. Competitive pressure resulting in cost reductions, time savings, and innovations in products and services are the current business and strategic challenges faced by every company, regardless of size or industry. Business decisions can have significant organizational and legal implications. These often impact both individual and collective labor law. In the context of restructuring or corporate insolvencies, social issues are increasingly coming to the forefront. It is an achievement of the social market economy that employees have been equipped with their own legal positions.
