I'm currently working in a place where you can see injustice from every angle. Here is one example.

In some departments, managers focus on some employees and push them to work hard while another group is doing almost nothing.

You can see them pretending that they are working when the manager is around and he just ignores them.

We already brought that issue to his attention and we are waiting to see what he will do about it.

I was hired in my previous company in a temporary position. Upon my arrival to work on my first day, my manager gave me a look, and I immediately knew what that look meant. I hoped that I was wrong, but I wasn't.

He kind of put me in a category of people who cannot/will not do or learn more than the basic stuff in the warehouse that involved only very physical stuff.

Other people who we were hired at the same time were converted to full-time positions except me regardless of timeless times I told him that I needed a full-time position.

I had to reach out to his superior to ask about my conversion, which was granted to me by the way, but that brought other issues because my manager told other managers from other departments that I was a snitch.

Until I transferred to another facility, I started to have peace of mind in that company.

Lesson: If your manager is not treating you well, tell him about the issue, and if he doesn't listen, escalate the issue to his superior/HR.

My company is huge and has hundreds of managers.

Unfortunately, they are the ones that make our job very hard due to their lack of communication.
They even make things harder by blaming us when nothing is being done.

With their incompetency, I wonder how they even got their positions.
