Getting Your Company to Migrate from IE?

RunningFerreT asks: "With all the recent warnings and recommendations on migrating from MSIE, I have come across a serious problem. The company for which I work doesn't want to, even after being informed of all the exploits and problems with Internet Explorer. Having the boss 'try out' Firefox isn't working: a single site looks bad, so IE must be better. Has anyone had success in convincing management types to switch from IE, to another more secure, standards compliant browser? If so, how did you get the job done?"
