You're going to hate me. But I have pulled this maneuver with employees before. I never did it, just for the hell of it, or to prey on someone that is a weak negotiator. But I have done it, because the talent pool grew significantly. I hope in your case, it's truly not personal between you and co-workers/bosses.
I can't really add much advise. But I can suggest one thing to bring to the table. Line your ducks up for this "chat" and know what positions are available, or promote quick within the company. Your best ammunition is going to be your experience within the company, and not just your skill(skill means little/nothing in an employers market because they feel you can be replaced.)
If you see a transitional position within the company that you want, and you think they would consider you for, then you might be solving another one of their personnel problems and saving your job. Again, this is just 'in addition' to the good advice given. If you can get your foot in the door, treat this like a semi-interview and sell them on how you are on the same page, can make the company better, blah blah blah. Don't make this out to be a; You're making a big mistake, type of chat. That never works.
