Countless studies have demonstrated the positive correlation between employee satisfaction and company performance.
If you're still in doubt, just ask any business school student or, better yet, read the opening chapters of Michael Burchell and Jennifer Robin's The Great Workplace: How to Build it, How to Keep it and Why it Matters.
The 222-page title makes a strong case for the 'happy employees mean productive employees' approach and includes a host of statistical and empirical data to back it up.
Burchell and Robin are both members of the Great Place to Work Institute, a global corporation that since the early 1990s has advised some of the world's largest companies.
The institute is also highly regarded among academics, but is likely best known for its Fortune 100 Best Companies to Work For list, which it produces annually.
Using real-life examples, Burchell and Robin highlight workplace strategies that continue to help the 100 Best get more out of their staff - strategies that, for the most part, stem from attentively listening to their concerns.
The authors' suggestions are structured around a slightly modified version of the institute's Great Place to Work Model (shown above).
