In Academia, is there any legal text or chart commenting about the desired behavior when a personal conflict could affect a set of professional decision?
A rough example of such chart would be a text stating that "we, academics signing this chart, engage ourselves to avoid as much as possible to let our personal tastes to influence our professional decisions, or to delegate the decisions to others if we are not certain to be able to ignore our personal tastes.". Such a chart, published by an association of academics and adopted by some universities and/or academics, would not SOLVE all instances of such problems, but would at the very least express the collective will to discourage such instances. (In the same way that a chart signed by students that they won't copy on others nor share their solution does not solve all cheating instances, but clarifies what is considered acceptable or not.)
By "professional decision", I mean a decision that you take on behalf of an institution or group of person, for which your job is to make the best decision for this institution. By "personal taste", I mean anything which applies when taking decisions for one's personal life. A neutral example would be a secretary having to make the "professional decision" of what food to order to department's celebration, and letting his "personal taste" influence his choice rather than his approximate knowledge of the tastes of the attendance. Extreme examples would be of senior faculty members using their political position to punish or reward junior members according to their personal values, independently of their professional opinion.
It is only human to be biased against someone with whom one had some conflicts, and only civilized to try to overcome this bias in the context of professional decisions (where one represents the choices of a community, as opposed to personal choices such as with whom you share a meal). One can think of some (uncivilized?) cultures where one does not expect anyone to even attempt to fight this bias, and of some (civilized?) cultures where letting this bias affect professional decisions (e.g. community related) would be frowned upon and considered as an abuse of power or bullying.
It used to be my opinion that academia was civilized and that most academics agreed to such an unwritten rule. It is my experience in my current setting that not only do occurrences of such conflict seem more frequent than in my previous settings, they are also considered normal there, and far from frowned upon, most often considered as "business as usual" or worse, a display of intelligence and strength. I assume that such an attitude could exist in other cultures, from other third world countries to even the US. I am wondering if Academia, which forms an international culture of its own, already has or could have a chart to curb such behavior to a more productive/collaborative/civilized one.
Note that I am not asking if some people in Academia abuse the power that their responsibilities yield (there will be in most communities), nor am I asking for general opinions about specific countries, culture and research areas. Rather I am asking if there are some reference texts which describes the desired behavior in such situation.
