Businesses often ask employees to complete projects that require they work as a team. Working together has many benefits, including the possibility to create new friendships, a sense of group accomplishment and distribution of responsibilities. Conversely, teamwork also may cause tension and anxiety among employees because of poor communication. Effective communication can eliminate much of the stress and negative feelings sometimes associated with working closely as a team. Business owners should encourage their employees to communicate with one another clearly when working together. This is especially important for smaller companies, whose employees often must work closely with one another.
