How do u feel witnessing co workers getting fired or forcing to leave?

I ve been working in small companies. Witnessing people come and go and sometimes my turn to leave. It s like hell people been mean to each others.

The salary isn't high and lot of things to tolerate.

I haven't saved much money and look back just wonder what s the purpose of all that.

I have seen so many people being mean and gross to others. Usually a way to express how much the boss or manager dislike the staff. Weird how they won't fire them directly.
Had to put him though bullying,
Another way showing how important money is. U can't be noble , have good heart without money.
