Then what the hell are you doing working at a call center?

Call center workers have one job: to read from the script. That's it. People who want to be creative do badly in those jobs, because they are not creative jobs.

If you take a job on the grill line at McDonald's, they will not care if you can make the most juicy, succulent cheeseburgers on your backyard grill. They will not be interested in hearing how you do it. If you start trying to do it at work, they will fire you, no matter how good your cheeseburger tastes. Because the goal at McDonald's is consistency. They hire you to make a burger to the McDonald's standard. Not to make the best burger you can.

And that's perfectly reasonable! There's no way to build a business on the scale of McDonald's while depending on the genius of artisanal burger chefs. It only works if you standardize.

The only way to turn out burgers on an industrial scale, in other words, is with an industrial process. And the same is true of turning out information via telephone. You could never find enough people to do it if each one needed to be a financial expert. The only way to do it is to use less expert people and give them a script to read from.

If that's not an environment where you thrive, I can understand. But the problem isn't with the environment; it works for what it needs to do (answer huge volumes of mostly basic and/or stupid questions). The problem is with you for putting yourself there. If you want to be an artisanal burger chef, McDonald's is not where you should be looking for work.
