Certain categories of performers face specific challenges in the practice of their craft. The nature of their profession – whether as dancers, opera singers, circus artists or others – has an impact on their working conditions and requires adaptations. For example, dancers, who have a highly physical job, will often have to stop performing in their late thirties and embark on a professional transition, which makes their access to vocational training of paramount importance. Dancers also rank among the most mobile of all performers and often struggle to reconcile the different social security, tax and administrative regimes to which they are subjected when working abroad.
