There's all kinds of ways to say you hated your job, but it's not always wise to to tell them how you really feel. There's always the chance that something said might affect your looking for another job. Why don't you just say that you don't feel you were suited for this job, and that's why you feel you should move on. It's not mean, and there's really not much they could read into, about your feelings about the job. But, you'll know why you're leaving, and it might even be helpful to write the meanest, nastiest letter to them, and after you get it out of your system, tear up the letter and throw it away. Then, you will have gotten it out of your system, without jeopardizing the chance to find a great job you'll love. Good luck on the job hunt!! P.S. Please don't mix up the letters!!!!
