Nonetheless, this has been done in many places and it led to ridiculous results. For instance, if you have a booth at a convention center in Las Vegas somewhere, just try carrying your own box from your car to your booth. Just try! You will immediately get screamed at that it's a union job.
Sure, but you can't attribute that to unions and say that's a universal negative effect of unions, the same way that you can't say knives are universally bad because they've been used to stab people in the past.
This is an example of how it specifically is. The deal/law with the city/state/municipality/whatever is that they can't hire someone who's not associated with the union. That results in ridiculous shenanigans I just described.
