Many companies focus on results and don't care how you feel. You get a paycheck and they don't owe you anything else, they reason.
You don't have to put up with it.
If you have a job where you are not respected or appreciated, it is time to move on. Perform as good as you can at your current position while you look for a new job, but begin now looking for a new job. Don't stay in a job where you are not satisfied with what you are doing.
People who don't feel they matter tend to make drastic changes. It is why people leave relationships. And it is the number one reason why people leave jobs.
There really isn't anything you personally can do if you have a boss who doesn't appreciate people.
The odds of you being able to do anything to change the person as slim. Do not fool with fools. Get out of the situation.
Basically, there are only two options. Stay and put up with it or leave.
Leaving is uncomfortable. But life is short, don't put up with a bad situation too long. Your boss won't change.
In a few years, what you are going through now will be a little detour.
Or, you can stay and put up with it.
Your problem is not your situation. Your problem is your decisions. If you stay in a bad work situation it is your decision.
