I am completely miserable

You ever work really hard at something, to put your blood sweat and tears into something and not have it turn out the way you wished it would have. I had a stellar extern this summer. I became a key part of a kitchen and really showed my myself what my own potential was. My chef gave me a stellar review along with general manager who told me to use him as reference in the future. I thought I did a tremendous job with my manual until today when I got it back. I failed my extern because e chef felt that Either me or the other extern at the site copied each others work. I am now seriously debating leaving the culinary institute and never getting a degree. I worked damn hard for this and in the end a person looking from the outside in didn't give me the time of day because another student form the same extern site had a few similarities in their manual. You might be asking what this has to do with management. Well many my point is that managers should only make reviews and critiques of other peoples work if they actually see for themselves the quality of their employees work. For all tense and purposes this school is my job now. Thus as an employee i feel i have received an unfair review and will more then likely quit if I am not given the proper time of day to defend my work. You figure a place that teaches the beautiful art of nourishing life would be a little more humble and compassionate.
