Soon to be boss!!!!

I work for a telemarketing company and one of my coworkers is about to become a coach. I cannot stand her especially when she coaches. There is no modivation to make sales and she is only worried about making herself look good. I really don't like that. I'm debating about putting in my notice when she becomes a coach. Don't get me wrong I love the pay and the job is simple enough but I'm not sure if I can deal with her being my boss. I've been at this job longer than her but i'm not a suck up and a person who gets into other people's business. A new hire gives me more modivation than her but they're still making her a coach! They were thinking about me but i guess i gave too much modivation or something because so many people gave me compliments when I ran the floor whereas others did not compliment her. Maybe if I tell my supervisor about what I'll do if she becomes coach then they might change their minds. If not I'll be looking for a new job. Anyone know of any job openings at a marketing job or anywhere for that matter just in case I need a new job?
