Preamble: ‘(2) The freedom to provide services includes the right of undertakings to provide services in another Member State, to which they may post their own workers temporarily in order to provide those services there. It is necessary for the purpose of the posting of workers to distinguish this freedom from the free movement of workers, which gives every citizen the right to move freely to another Member State to work and reside there for that purpose and protects them against discrimination as regards employment, remuneration and other conditions of work and employment in comparison to nationals of that Member State.‘
