It depends on the level of detail the company wants to know. With HTTPS, the firewall cannot see the full URLs retrieved, but it knows the site the user connected with. DNS queries may also reveal this if you log those in a way attributable to particular workstations. If the connection is to a VPN service, the firewall will not know what sites are accessed through that tunnel. Companies that want to know/control everything run a local proxy which performs a "man in the middle" attack that cannot be bypassed.
