So here's the story. I work for big company. When I say big, I mean real big. Like 35 Billion dollars a year big. Anyway, we'll call this company "Mother". So anyway, Mother has alot of different divisions. One of which I used to work for. We'll call it division "A". Well, when mother decided to close division "A", everyone one was jumping ship like it was sinking. When the dust settled, who was left standing there? Me. Thats who. I hung in there. I was getting paid a decent salary and the company was treating me well, so I stuck around till the end. In fact, I very quickly became the "Cleaner". In other words, I went around to all the projects that had gotten run into the ground, and found a way to get them finished and minimize the damage. So when the last project was done, the president of the "Western Region" went to the head of Division "B" and told him, "Look, this guy is real sharp, works hard, and I dont want to lose him. So find aplace for him in Division "B"."
Well, as it turns out, I got brought into "B" in similar position, but I have to "work my way up" again. So the new position came with about a 20% paycut. Now, admittedly, I dont know shit about Division "B" and what they do. So I was willing to take the cut (temporarily) until I was groomed into the project managing machine that I was, and know that I can be.
Here's the problem. The head of Division "B" is an ego-maniac. He is a self proclaimed genius and expert. He knows it all, and no one else knows shit. So when the Western Region President told him how great I was, how smart I am, how hard I work, and what a tremndous asset to the company I've been, instantly he hated me. So here's what he's done. he took me on, and has consistantly given me remedial tasks, no guidance, and no respect. He has kept me as an "outsider" in the division, and doesnt hesitate to tell others he does see what all the fuss was about. That I dont know my ass from a hole in the ground. In a nutshell, what he's done is prove the Western Region president wrong about me, by holding me back while other "newbies" have come in and been groomed.
So why am I still here? Well its simple, I'm a father and a husband. I have people who depend on me. I cant just walk. But this has been gong on for about 4 months, and with the paycut, I went from debt free to phone ringing off the hook with collectors. Problem is, My wife's health is failing, and I need the Medical Insurance. Not to mention my son is chronically ill, and he needs the insurance too. All of which my boss knows, so he knows theres nothing I can do. So here I am, up to my ass in debt, in a job that will NEVER go anywhere for me, and I FUCKING HATE THIS PLACE! Coming in everyday, trying to pretend that I give a shit, when I dont. Not really putting any effort into my work because I know its going nowhere, and subsequently not doing it very well, which just crates more hassle, and more resentment. What a vicious cycle!
