These days I'm not good at work. My boss doesn't behave good and he is always sad. He is trying to enforce us to develop as much as we can.

I asked him about it and he told me: Everything is going to be OK. "I'm normal and there is nothing to worry about", he said.

I think, he doesn't know how a manager can effect on his/her employees with these kinds of behaviors. When a manager is sad, all employees think that there is something wrong with the company for example, one of the company's projects has been failed.

In my opinion, a good manager is a person who always behave well at work. because he/she is a person that can make the company happy. When a manager is good, so the company is good too.

Because of these changes in our company, I decided to change it. So a manager may lost some of his/her employees.

I got an advise for you:

If you want to start working in a company, try to know the manger(s) as well as you can.
