In many organizations you will see, the organizer says they want to work together or make the decision together. In the end, you will see, they have only approved their own decisions.
Or sometimes, they ask your opinion on some matter. Actually, they just want to hear praises on that issue. If you ask to change or add something to it, they won't like it. There is no chance that you will see any slight change to keep your opinion. Moreover, from next they might kick you out from that kind of meeting.
No matter how many times they ask all people to join the leadership or work together. They will only elect their own people. They will always give you a genuine cause how it is impossible to take you in the team.
So, I think, in these situations, I better just watch and learn. When no one wants to hear from me, then what's the point of talking?
