Well, there's going to be two possibilities, each with their own
Copy everything to work. This leaves you open to sniffing by your workplace.
If you trust your workplace not to invade your PC for any reason, then this is
a good option. It lets people use the same key for different purposes. Keep in
mind, though, that some employers will scour your machine after you leave, to
see if you were doing anything. And they might not give you the chance to
clean it, leaving your keys vulnerable. Advantage, though: People only need
one key to check if it really is you.
Make new work keys, and do a cross-signing (ie: sign work key with home key,
home key with work key). Guarantees you the safety that copying to work does
not. Disadvantage: People need both keys, or need to be able to trust you
completely to act as introducer for your other key. Either, way, it's slightly
more difficult for them.
The end result? You have to decide which is worth more to you: Security for
your keys, or convenience for your keys. As you are looking at encryption and
signing in any fashion, you should most likely choose security.
