It wasn't until the 1930s that the idea of worker satisfaction entered the working world's psyche. Before then, the prevailing attitude was simple: "You work for us, we pay you." Worker dissatisfaction was the norm, and many industries rose and thrived on taking advantage of the working poor. It wasn't until the realization dawned that a healthy worker is a productive worker-thereby impacting the company's bottom line-that the focus on worker satisfaction began to gain traction through industrial psychology and early management theories that recognized the importance of employee well-being for productivity.
