Colleagues are those explicitly united in a common purpose and respecting each other's abilities to work toward that purpose. Thus, the word collegiality can connote respect for another's commitment to the common purpose and ability to work toward it. In a narrower sense, members of the faculty of a university or college are each other's colleagues; very often the word is taken to mean that. Sometimes colleague is taken to mean a fellow member of the same profession. The word college is sometimes construed broadly to mean a group of colleagues united in a common purpose, and used in proper names, such as Electoral College, College of Cardinals, College of Pontiffs.
Roman collegiality
In the Roman Republic, collegiality was the practice of having at least two people, and always an even number, in each magistrate position of the Roman Senate. Reasons were to divide power and responsibilities among several people, both of prevent the rise of another king and to ensure more productive magistrates. Examples of Roman collegiality include the two consuls and censors; six praetors; eight quaestors; four aediles; ten tribunes and decemviri, etc.
The term collegiality also refers to what critics call a tendency in the Roman Catholic Church for conferences of bishops (acting as a "college of bishops") to attempt to impose a real authority over their own membership. This is contrary to what critics perceive to be the Catholic belief that only the Pope has authority over other bishops. One of the major changes of the Second Vatican Council was to encourage Bishops confrences, which critics felt could potentially destroy the independence of each Bishop (by de facto forcing individual Bishops to go along with a majority vote of a conference), as well as undermine the authority of the Pope (by a confrence, synod, or council claiming to have some authority over the Pope).
Colleagues are personally responsible for their training, time commitments, performance and participating in and contributing toward achieving the Mission and practicing the Principles.
When one colleague perceives that another colleague is not adhering to the Colleague Principles, or not acting in a manner conducive to achieving our Mission, that colleague shall privately discuss the matter with the other colleague as soon as practical and attempt to resolve any differences to their mutual satisfaction.
If either of the colleagues do not feel the matter has been resolved to their satisfaction, then both of them shall agree to discuss the matter, together, with one other colleague as soon as practical and attempt to resolve any differences to their mutual satisfaction with the help of the third colleague.
