It sounds like you guys and gals in SFO should launch an intervention and speak to Oscar. Typically CEO's don't get involved in this type of stuff, but I wouldn't be intimidated into NOT doing something if you legitimately feel that there are unfair politics or agendas that are getting in the way of ethical decision making and more to the point, basic competence of on sight management personnel.

Typically management carries each other's water. However, if it's really bad, the rats may start abandoning the ship and volunteer to go back to the line instead of serving with a dirt bag in the office. Most good folks tend to vote with their feet rather than be "guilt by association" with a person that is making them, and/or their office look bad.
