Professors are employees.  Well paid and privileged employees, to be sure.  But employees nonetheless.  A contract governs the relationship between these employees and the U of O.  In Oxford or Cambridge etc, , centuries ago, the relationships were much different.  Get over it and do what you were hired to do; earn Grants or teach or both.  If you aren't doing either of those, you are a mere parasite and not even a symbiotic one at that.  Pontificating is not a required part of your job description.
