I think this needs to be resolved across industry. The so-called "leadership" should learn that not all fingers are equal but every finger has use and value. Similary not every employee can be a leader and extrovert. It is the leadership's responsibility to identify and make use of "silent souls" on a team to greater effect. In my career I have seen people who are introverts to be very capable when given a right environment; in fact they exceed others on the team. Forcing people to be what they are not is not a good leadership practice.
