People are not treated equally or fairly, there are examples of people being promoted to management positions only for being drinking buddies with a director.
One of the directors in the UK office acts very unprofessionally on a regular basis, this director has shouted and threatened people in meetings and accused members of being unproductive while other members in the same team who are less productive seem to be humoured and be able to "get away with murder" without any repercussions. This director creates a split in the team due do not being able to separate personal from professional relationships.
