If you have `ssh` access to the respective server at work you can start the emacs server at work using the command (with the respective username and server host name):

 ssh -X [email protected] emacs --daemon

EDIT: If your emacs is already started on the server than just kill it and add automatic server start in your .emacs:

 $ ssh [email protected] killall emacs
 $ ssh [email protected] sh -c "echo '(server-start)' >> ~/.emacs"

Now you can start emacs in daemon mode as described on the first command. The added server-start command would enable the server on the opened emacs session.
