Ah, I miss the heady days of the FT inside operations, when the union was far stronger. In those days, they used three tactics to control inside management:
1) Discipline an hourly on say, PD-4, and the Steward disagrees. Through a system of winks and nods, someone would yell "Happy Birthday PD-4!" and every package out of the sort aisle would go to PD-4. In the 30 seconds it took for management to run up to the aisle and catch someone missorting, the sort aisle would go back to normal, but 200 missorted packages were already on their way to jam PD-4.
2) Discipline someone for production. Same system of winks and nods. Someone yells "SUPER SORT!" - every unloader and sorter would double their speed, following perfect methods and the sort charts, essentially doing the job TOO WELL, for about 5-10 minutes until the sudden surge in flow shut down the outbound PDs. Then they'd stand around and laugh.
3) God help you if you didn't bring the key - entry employees his / her coffee just the way they liked it at the head of the old traylines. There was no logging of key entries, and if they were in a bad mood, packages could end up anywhere.
Mgmt needed more diplomacy then...
