If it were a small mom and pop business, maybe. You can usually find compromise when the numbers are small enough that you can sit the entire company around a table and hash out your grievances.
But we’re talking about a big business. One of the (if not the) largest businesses in the country. In big business it is really hard to get everyone on the same page at the best of times. But in this case every worker is the employer, which complicates things even more. If the accounting department says, “Nope, deal with it.” what are you going to do? Say “You’re fired” as they say “No, you’re fired!”
You’re right that being an employer doesn’t magically give you control over other people. They’re going to do what they want, even in small businesses, but especially in big businesses. If the workers don’t want to fix this, what are you going to do? It is not going to automatically fix itself. Only the workers can fix it.
