Speaking or the bad welds.
My son was a correction tech at Mack Trucks. The grilles were falling out of the trucks at the end of the line. So he went to investigate why all the grille screws were stripped. He watched the young guy installing the grille.

The man/girl/it/person or what ever pronoun it used was pushing as hard as it could and pulling the trigger on the gun and held it flat out until the screw went in.

My son asked him, Why are you pushing so hard? The young person said that was the only way the screw would go in. So my son grabbed the gun and tried. The gun was on reverse!

These companies hire anyone that will show up to work. Its hard to find young people that will even show up to work anymore.
