If your employees are friends with each other, they very well may enjoy having a drink with each other after work for an hour despite seeing each other so often. The reason is that they don’t actually see each other that much while working. It’s like saying students would rather go home to their family because they already see so much of their friends at school. It is perfectly possible for coworkers to be friends with each other, and that DEFINITELY should be a goal for building a company.
