Since 1995, employees have been recognized across the world on a larger scale. However, as one of the main sources and stakeholders in businesses are those we employ. These are the people who support the efforts and goals on a daily basis, those who believe in the mission and the vision of the company, and those who ensure things are kosher with partners, agreement holders, customers, clients, and others.
Obviously, employees exist prior to the national recognition back in 1995 to appreciate employees. Therefore, the first Friday in March should simply be an extension and addition of moments to express your appreciation for your employees. Please remember the important people in the company and celebrate them accordingly.
