I started as a package handler around peak season. I was very enthusiastic about the job. I told myself "I'm gonna do the best job that I can so that I can leave a good impression on my PT Supe and my Full time Supe because they have my best interests at heart!"
So from about October to January I worked my ass off. Like better than anyone on my belt.
And then I realized that I am breaking my body down for absolutely nothing. The supes don't care about you lol. And if you work hard and one day work a little slower then they will be on your ass.
My dumb naive ass sobered up to the reality real quick. And now, I take my time, I work safe, and I work normal. I don't try to impress anyone. And I simply collect my paycheck and leave.
They are just packages. Don't kill yourself over them.
