After searching for a job for months, I gave up and took a job outside of my field. Surprisingly, I actually like working in manufacturing, but one of my coworkers loves to start trouble. He has been there since he was 20 years old and whenever threatened by someone's work ethic. He will cause chaos. Sadly, they will believe him over everyone. What's bad is I have become his main target due to our management showing recognition for my work ethic. I'm afraid I am back into corner and I have no defense! Help!
