According to the comments you made earlier with a lot of intensity, you in your organization have learned over time that each service counts, that everyone must make themselves heard. I think that your words were the same as those you used a few minutes previously. You even finished by saying that it seemed obvious to you.
Since we know that political parties are organizations with their own interests, is it really up to them to make the final decision on such an important issue? You work for a union. When the time comes to vote for a strike or for better working conditions, for example, do you really consult all your members to ask for their opinion? When all is said and done, wouldn't you be in favour of citizens being able to express themselves?
