When calculating a maximum assignment period laid down in national law in order to give specific expression to the criterion of ‘temporarily’ in Article 1(1) of Directive 2008/104/EC, (2) must, in the event of a transfer of undertakings, the transferor and the transferee always be regarded as one ‘user undertaking’ within the meaning of Article 3(1)(d) of Directive 2008/104?

2.

If the answer to the first question is in the negative:

When calculating a maximum assignment period laid down in national law in order to give specific expression to the criterion of ‘temporarily’ in Article 1(1) of Directive 2008/104, must, in the event of a transfer of undertakings, the transferor and the transferee be regarded as one ‘user undertaking’ within the meaning of Article 3(1)(d) of Directive 2008/104 if they belong to the same group of undertakings and the same temporary agency worker is assigned without interruption to the same job?

3.

If the answer to the first two questions is in the negative:

Must the transfer of a user establishment be taken into account in the context of monitoring whether, in the case of successive assignments of the same temporary agency worker, the duration can still be regarded as ‘temporary’ (Article 5(5) of Directive 2008/104)? If that question is to be answered in the affirmative, how is that transfer to be taken into account?
