Charge a few low level postal workers, and sweep the rest under the rug. Just like the Epstein hit.
Postal Union thugs will go around and check postal union worker’s yards to see if they have political candidate signs in their yard. Only approved dem candidates allowed, put up a Republican candidate sign, union will show up and “coerce” you to remove it. When I got hired as a letter carrier, union thug showed up at office to get me to join the union. After his presentation, I asked him about 5 to 10 political questions, about half was answered “no you are not allowed do that”. I didn’t join, and am happy I didn’t. Basically he answered you must tow the union and dem party line or face consequences. The postal union is full of narcs, eagerly waiting to file grievances against co-workers who aren’t in lock step with the union. This has been my personal experience as a 25+ years letter carrier. I work in a very small post office, I know a lot of carriers in the other cities and small town post offices nearby, I wouldn’t work in their office for 10x my salary.
