This document, a compilation of opinions, because it is too pretentious to call it a book, reflects the result of the lobbying against the EU of the association that I have the pleasure of presiding, ASPERTIC. The latter made enormous efforts to get Directive (EU) 2019/1937 of the European Parliament and of the Council, of October 23, 2019, on the protection of people who report infringements of Union law.

The methodology for using this document is simple. In this prologue are the conclusions that have been reached in each of the opinions that have been included in the work. We understand that, for practical purposes, it is easier to read the conclusions and then seek the substantive argument in each case.

Also at the suggestion of several people we have included some previous notes so that you can better understand what it is and what happens in Brussels; in other words, how things cook in the main center of power in Europe.

At the end there is the appreciation of those who have contributed their grain of sand to this set of studies, being considered, who are also, at least by me, co-authors.
