Pay Raise?

I could be getting a promotion at work! Apparently, one of the employees isn't working out so I may take his spot as assistant manager. If so, I would gain an extra shift and a pay raise and a few more responsibilities. I'm still unsure if this is what I want to be doing since I'd already be going to school full-time. A full-time job might be a little much. I'll think about it another day or two before I officially make a decision but I'm at least happy with developments so far!
