Nobody likes a person with a bad attitude. This applies for employers as well. The very definition of being a lady or gentleman is having an exemplary attitude. If you are proud and vain at work and are constantly demanding for raises or promotions, you probably will not get them. It is important to know that there is a difference between being a driven go-getter and being a proud employee. A proud employee should do their best to work on their attitude and become more humble to increase their chances of getting promoted.
