Everyone comes to a certain job for a different reason. Maybe you see it as a stepping stone in your career, where you will gain experience and make connections. Maybe you just need something to tide you over for a couple of months while you look for something more permanent. Maybe you know somebody who works there who gave you a foot in the door. The paths that you can take toward the same job are infinite. This is why we sometimes clash with our coworkers. We might all be there for different reasons. But whatever it is, you shouldn’t look down on anyone else’s reason to be there. 

Maybe you work a certain job just to have a little extra cash, and you don’t depend on it for your livelihood. That doesn’t mean that your coworkers don’t. They might need every red cent from that job to keep themselves fed. It is not anyone’s place to judge that situation, since you never know if you might be in it yourself one day.
