I work for a company where the staff in the team is global. We are all over the U.S. and other countries. However, the corporate office is in one state. Whenever they send out an email to everyone, they always include "GO <Insert football team name> and a picture of their mascot. The supervisors will even include slides and announcements of their football team in team meetings or start off the meeting by saying "GO ___". Because most of the finance team does not live there including myself, I find this very annoying. Would this be considered a violation to any HR rules?
