When I am facing a lot of pressure at work my back and neck will start to hurt. Sometimes these tention is the result of too much work. I have too many things to do because my supervisor is on my back all the time. In other words, my employer is always telling me to do things. Sometimes I want my employer to get off my back. I want her to stop criticizing me and making too many demands on my time. I can not say this, however, I would never turn my back on her and refuse to help when there is a need. If I did refuse to help, my supervisor might say bad things about me behind my back. She might criticize me when I am not present. This would surely be a step in the back. It is never kind to unfairly harm or say bad things about other people.
