Article 4
1. The transfer of the undertaking, business or part of the undertaking or business shall not in itself constitute grounds for dismissal by the transferor or the transferee. This provision shall not stand in the way of dismissals that may take place for economic, technical or organisational reasons entailing changes in the workforce. Member States may provide that the first subparagraph shall not apply to certain specific categories of employees who are not covered by the laws or practice of the Member States in respect of protection against dismissal. 2. If the contract of employment or the employment relationship is terminated because the transfer involves a substantial change in working conditions to the detriment of the employee, the employer shall be regarded as having been responsible for termination of the contract of employment or of the employment relationship.
