In such a fast-paced, high-stakes environment, keeping up a positive attitude can sometimes feel like an arduous task. But the one simple yet powerful tool that is usually overlooked for improving workplace morale and productivity-the smile-can go a long way in changing team dynamics, from a gentle greeting to an expression of support or a response to a colleague across the table. Smiles will be the action to build trust among individuals, avoid stressors, and unite them for work. As small as it may seem, a smile is an excellent sign of hope and team effort, and may further lead to a triumphant day of work.
