Open back, Insert spine

So....I finally told my boss (10 minutes before the end of the day) that I was looking for another job. Back fill - I posted my resume on Monster & CareerBuilder this weekend....and got a call on my cell from World Savings this afternoon. I have an interview with them Friday morning. I'm not terribly excited about it...but what the heck. And before you ask....no, nothing further from Planned Parenthood. So, after pondering my options - I could call in sick (I don't like lying), I could cancel the interview (what if nothing else comes up) or I could bite the bullet & just tell my boss what's going on. So.....I told her. The 1st thing she asks, is if it's about the money or commute. I said NO. She then asked what she could do to keep me....I said give me more to do. She asked if I was leaving because she was. It was all I could to to not say NO, I'm leaving because you won't! I told her that I was frustrated, that I felt like if I stayed there that I would be doing the same thing with no hope of a future. I said that I knew I wasn't management material at this time....but that I did not want to be doing the same thing 3 years from now. She asked what I did want to do.....I said more work, more administrative stuff, research, projects, reports, spreadsheets.... I told her that I wanted the office that she told me about in March & the payroll upgrade that we've been talking about since February. I told her that I was better than what I was being given, that I was capable of so much more. She agreed with me.....ok, so if she agrees, why doesn't she use me?? She also said that she didn't want to 'hold me back' or make me feel like I couldn't be honest with her about any of my plans. So....I guess we'll see how things really fall tomorrow, after she's had the evening to think about the ramifications of what I'm doing. To be honest though, I probably would stay if they'd just follow through on what they said they would do.....hire a clerk, get me off the front desk & into an office....and upgrade the damn payroll.
