Well after my experience with unions in Philadelphia, I’m pretty confident in saying that it varies. I worked for a company that held conventions. We wanted the flag of each attending country to line the entrance hall and it took coordination with FOUR unions. I am not exaggerating.

One union to bring the pallet to the hallway

A second union to place the flag bases

Yet another union to place the flags in the bases

And the last to remove the pallet/packaging (not the same as the first!)

I found this out when I nearly got tackled after putting a flag in its base.

On the flip side, my friend’s labor union secured a (permanent) $5/hr raise during COVID.
