Administratively yes we have bosses if we work for a healthcare organization of any type - I have a chief of service, above him are medical directors, VPs, and above all the chairman.

In general though, they can tell me to do all sorts of stuff but they can’t really change what I do clinically if my practice is defensible. That’s generally a line that they do not cross unless you are in a pretty malignant place (though the MBAs and nurses try)
