There are some places where I don't really have an opinion; if you work in, I dunno, pet grooming, and you and your employer agree to... "shared custody" of a device then sure. But I'm not sure that's possible in some fields. As I understand it, financial companies are legally mandated to record every single message sent/received on the machine so they can prove that nobody's doing insider trading or whatever. I would kind of expect something similar for medical field companies. I'm open to suggestions, but I can't personally see a way to uphold that obligation while giving the employees privacy if they want to use the company device to ex. check their personal email.
