‘Employee empowerment’ isn’t just a trendy phrase

The Saylor Foundation says “many businesses … looking to improve employee productivity and their overall performance believe that empowering employees will help them achieve this organizational goal.” Empowering employees is being recognized as an important part of management that means improved productivity, satisfaction, collaboration and quality of work.

For example, several on our Great Companies to Work For list cite empowerment as a main segment of their employee programs, including Regent Bank, which allowed its employees to collaborate and come up with a company approach to customer service, and Red Crown Credit Union, which started in 1938 because an employee of Stanolind Oil & Gas Company used a shoe box in a desk drawer to “bank” employees’ funds.
