Communication on the part of a town council in the organs of union representation of information related to the extraordinary times of its staff

A town council can communicate the information related to the extraordinary times of its staff in the organs of union representation if he uses a numeric code in substitution of the name and surnames of each worker and guarantees the no identification. Likewise, this information together with the description of the job can communicate them if it is about jobs that they count on a number of workers enough extense, in such way that to identify each worker it requires disproportionate deadlines or activities.
