You really aren’t the smartest tool in the shed, are you? The teamsters need UPS more than UPS needs them.
Although they might think that, I would like to see the shell of the company that once was after they have to replace 200,000 workers.
It would take them so long to replace experienced drivers with untrained newbies that the company would lose 75% of their business before they got the new drivers up to speed on all routes. They also don't have enough management in place to oversee the training of so many people at one time.
Suffice it to say that you should really consider more of the facts when you make such a grandiose statement.
