1. The transferor's rights and obligations arising from a contract of employment or from an employment relationship existing on the date of a transfer shall, by reason of such transfer, be transferred to the transferee.

Member States may provide that, after the date of transfer, the transferor and the transferee shall be jointly and severally liable in respect of obligations which arose before the date of transfer from a contract of employment or an employment relationship existing on the date of the transfer.

2. Member States may adopt appropriate measures to ensure that the transferor notifies the transferee of all the rights and obligations which will be transferred to the transferee under this Article, so far as those rights and obligations are or ought to have been known to the transferor at the time of the transfer. A failure by the transferor to notify the transferee of any such right or obligation shall not affect the transfer of that right or obligation and the rights of any employees against the transferee and/or transferor in respect of that right or obligation.
