@deannali,
Please tell us your operating system, on both computers. There are a few options for you

The simplest thing to do is to set your ipod options to manually manage music and videos, but in the long run this could become confusing.
So .... Personally, I would enable disc use on the ipod, load the new "work" tunes on the ipod as data. Go home .. import the new songs into "home" itunes and load the ipod from home.
I believe you can sometimes sync both computers' itunes, but not sure how .. They may both need to be macs ... a possible investigation looms
