Southwest Airlines has a unique culture focused on investing in front-line leaders and hiring for attitude over skills. They train supervisors who work alongside employees to coach rather than discipline. New employees go through ongoing training and a trial period. Job descriptions are flexible and employees help in different roles. Conflicts are used to build relationships through communication between parties. Broad performance metrics are used rather than focusing on accountability. Unions are treated as partners rather than adversaries. The culture emphasizes fun, importance of work, and that people are important.
