Poor investment

How long do you have to work for a company, break your back, and show loyalty before they do the same for you? The post you are about to read is one that may get me FIRED, but I have made a promise to my readers that I will present the information without reservation, and I intend to keep my word, just as I have for 2 years with my employer.
I was literally 3 weeks away from graduating when having a discussion with my supervisor about the conflict with working 6 days a week while trying to finish up school. Not only was there no compromise, but I am not finding myself trying to take my final exams and finish my terms papers around 46 hours a week of work. I literally carved it down to one necessary day off in order to finish up school, and I was denied. One day! It just goes to show what kind of economy we are in, and what kind of businesses are out there. I am left to continue my job as I always have before. I do my job, and I do it well, but I am not a robot. I have thoughts, emotions and feelings, and therefore I write blogs. Is anyone out there that can relate?
