re: How does one go about negotiating salary?

I told him yesterday that originally my idea was that I was taking two positions, one senior and one Jr at different locations (both traveling for me since I'm not at either). They are wanting me to do project work at another facility and basically develop a program for a huge company, way outside of the two positions of work I'd be doing for them. He basically has work overflowing and asked if I could start Tuesday. Told me think about it over night, and said he'd call today. I don't think I'm willing to walk out on my current company like that, I need to give them at least a week just to get things sorted, and my projects assigned with all of the background work.

I haven't brought up salary...but today is likely the day. "Can we talk about my salary..."
