For example in a hospital, there is no good reason for employee to use Tor on work computer.
"I'm a doctor in a very political town. When I have to do research on diseases and treatment or look into aspects of my patients' histories, I am well aware that my search histories might be correlated to patient visits and leak information about their health, families, and personal lives. I use Tor to do much of my research when I think there is a risk of correlating it to patient visits. - Anonymous Tor User"

I would argue that hospitals and other public settings are actually more in need of higher privacy in electronic communications.
Imagine a physician working on, say, Scarlett Johansson's health issues; he periodically sends this data to the specialist that will run some test, and a creepy sysadmin finds out. Should he be able to MITM those comms, and resell the info to newspapers (or worse)...? Nope; the physician should have perfect privacy from network operators.
