Coworkers are trying to get me fired. Should I tell my boss or ignore the situation?
I've been at the company for seven years now. I work with four other people, one has been with the company for five years and the other two are young (first job out of college) and have been with the company under two years. I have a different title; different job duties, more education, more experience and have thus received several promotions in my time at the company. I have the highest rank out of my group. I’m not the manager but our real manager is not even in the same building and therefore has very limited interaction with us. He’s passed all his responsibilities to me so I’m responsible for managing the group even though I don’t have the title. Even my bonus is based on how I keep the group on task, up the productivity of the group, etc. The two newer employees have had issues with spending a lot of time on the internet, texting, personal phone calls and it has come to me and the other employee to pick up the slack. I’ve contacting my manager about the situation but nothing has been done. Needless to say the atmosphere in the office is not pleasant; there are two of us working our butts off while the other two are chatting with their boyfriends on the phone. I’m supposed to stop the bad performance but I have don't have any power and they know it! They could care less about my bonus.
I recently overheard a conversation between the two newer employees (they didn’t realize I was working late and was still at my desk). They are trying to figure out a way to get me fired. They said lot of horrible things such as “I want to murder her” and “she is a control freak and makes us look bad.” There is a lot of resentment; they don’t understand why the two of us who have been with the company longer don’t take advantage of having a absent manager (they lie about their hours while we put in extra time, they take an hour and a half lunch while I take a half hour, etc).
Any how, this leads me to my question-should I tell my boss about what I overheard or should I just ignore the situation? I’ve been with the company seven years and have never had a less than perfect performance review and I don’t want to validate their pettiness but I also want to protect myself from slander. Should I start documenting the poor performance some how? Should I confront my coworkers? Any advice would be great.
