It would require some sort of remote management program, so best to clear that with the IT people at work first, before you go trying to install software on a work computer. You should also consider the security implications of having such a program running on your home system.

When at work, maybe you should just use something like Google Groups. It may be less than ideal, but it's functional, and it saves having to clear things with company IT and exposing your system to the potential security risk of a remote login. All it requires is a web browser, which presumably you already have on your system at work.
