If your employer has uploaded documents to Planday you can view them by tapping Documents in the More section of the app.
There are three main types of documents: Payslips, General, and Contracts. To keep your personal data safe, Payslips require a password to view as do your contracts which are further split into Signed and Not signed. In General, you may find standard documents uploaded by your employers such as employee handbooks, tutorials, or manuals.
