In short, camaraderie promotes a group loyalty that results in a shared commitment to and discipline toward the work. Camaraderie at work can create “esprit de corps,” which includes mutual respect, sense of identity, and admiration to push for hard work and outcomes. Many companies are engaging in corporate challenges, such as bike to work day, wellness competitions, community service events, and other activities to help build a sense of teamwork and togetherness. Best practice companies also communicate widely about corporate goals and priorities to unify everyone.
