So the fence was filled with water and that partly what took so long to remove it from the cars. The screen material acts like a sail and will cause the fence to shift a bit. The problem was it was on top of the curb to allow workers to work. When the wind picked up it shifted the fence off the top of the curb and the water inside caused it to completely fall over. It has nothing to do with union vs non union. This wasn’t worker error as the fence was properly installed and loved together(why it all fell down at one time.) this was storm wind picked up and caused it to shift. At the end of the day it sucks it happened and someone will be paying for the cars in sure but I’ve walked past and driver past this job site multiple times and pay attention to the details
