In the Netherlands, the legal consequences of a transfer of undertaking are especially unclear - or even: unreasonable - in the case of collective labour agreements. At the current state of affairs, employers will be bound by rights and obligations contained in those agreements even after the agreement itself has expired. Moreover, employees may, under certain circumstances, pick their labour conditions from different collective agreements and pick the most favourable ones (cherry picking). The author seeks to find a solution to these and other problems relating to the transfer of collective labour agreements.
