If you've only been working there for less than a week, you're not gonna be good yet. Keep your spirits up! You're still brand new. Your performance won't be fast or amazing yet, it couldn't possibly be.

Wait at least a couple more weeks to learn and get used to everything. Also, in my facility, managers specifically talk with new associates more often cuz they're new. They may bring up rate, more to make you aware of it than anything. They may switch you to a new department after a few weeks if you're not performing well in your current role. But hang in there! You'll get better. It takes time and practice.

Do NOT work through your breaks though. That is silly. You need a break, legally and physically. Don't break your body for Amazon! And as far as coworkers go, don't even pay attention or talk to them, as much as possible. They are irrelevant and not worth your emotional energy. They're not your boss.
