The municipal policy for the use of digital information systems and devices must cover clear rules on the management to be made of the personalised corporate email account, and on the access to the information contained in it, both for the purpose of ceasing the employment relationship and in the event of temporary absence of the worker. It must also include specific provisions regarding the proper use of information systems by its staff and the control that the City Council can make of them to ensure their safety and good functioning. With regard to requests for access to and copying of e-mails by ex-workers, the observations made in this opinion must be taken into account.
