  The simplest way is to pass the ssh param -R and forward a remote
port of your home computer to a local port (22) on your work computer.
 While ssh is connected, it will forward any given ports to any given
ports, and this would allow the ssh connection to say 'MyHomePC Port
9876 should be forwarded to MyWorkPC Port 22'.  You could then ssh
from home INTO your home PC using a different ssh port, and magically
have it appear as an ssh to your work computer.

  All of this will only work while the ssh from work to home is open, however.

  Depending on your work environment, you may not want to be caught
doing this.  In many cases, if you are, some could consider it grounds
for termination.
