Only if you are allowed to work in the Netherlands you can apply for jobs via Temper. Anyone with the Dutch nationality or nationality of a country of the European Economic Area (EEA) - except Croatia (only from 2020) - is allowed to work in the Netherlands. When you do not have this, you have to have a valid residence permit with the mention 'Work freely allowed'.
To determine whether you can work in the Netherlands, Temper asks on behalf of the clients where you will respond to shifts to upload a scan of your passport or identity card. Your identity is mentioned on this document.
