You will have to ask the administrator at your job how that's handled. Most
companies will not allow non-authenticated computers/users to touch their
networks. Most will use a VPN to allow remote access but usually over their
own equipment, meaning you would have to have a company-issued and configured
laptop. Unless they are using Citrix to allow people through a remote portal
or OWA, in which case you could use your home/school computer. Only your
workplace can answer your questions.
