Childish Office Antics

I've been exhausted all day. Maybe I was up too late watching the debate. Maybe staying up and talking to Hubby before going to sleep was too much effort. Whatever it was, I have had zero energy today and I also developed a migraine about as soon as I arrived at the office. Coincidence? Perhaps. I think it is cause and effect. I think my office setting is extremely unhealthy. I think it not only affects me, but also affects the well being of my coworkers. Why do I feel this way? Because we must answer to a complete moron of a "supervisor." She has the mentality of a 6 year old and the maturity to match. How she got her position I'll never understand. Why they keep her on when it is known throughout the department how off the wall she is; is an even deeper mystery.
The mere sound of this person's voice makes my skin crawl. Now that is not good. She has zero redeeming qualities. She tells outright lies about me and my coworkers to our department director and we constantly have to defend ourselves. The director knows she's making it up,but never calls her out. He seems to think this will all magically clear itself up. I need to find a better job. This atmosphere is taking its toll on me and my health. I used to enjoy my job, but for the past 4 years it has just gone downhill and I can't leave the department. My only chance is to find a job on the outside.
