This just in. The secretive Unity caucus oath has finally been reveled and must be memorized by all preferred Unity members if they want those high paying union positions, double pensions, and all expense paid travel to cities throughout the country. The Unity oath pledge goes as follows:

I also pledge to keep my opinions to myself and not leak out any information, confidential or not, to the rank and file. As whistileblowing will result in automatic excommunication from the Unity caucus and revocation of all benefits awarded to Unity caucus members.
Finally, I pledge to defend the union and the leadership positions at all protests, conventions, and committees, even when it runs counter to the members concerns"
Of course there may not really be a Unity oath pledge but if there is one it would very much resemble my best guess of what it would be.
