Adapting the workstation sheet
The user undertaking is the company that wishes to occupy a temporary worker. The user undertaking is therefore the client of the temporary work agency.
PI uses the term "user undertaking" because it is the terminology that is the closest (in English) to the one used in the legislation on well-being at work (Belgian Code on Well-being X.2) = Utilisateur/entreprise utilisatrice (in French) or Gebruiker (in Dutch).
