Your manager might be the key to your company's bottom line. Gallup's extensive research shows that quality managers don't just make employees happier—they directly boost financial results.


The Numbers Don't Lie

Gallup studied thousands of business units and found striking patterns. Teams with engaged managers see 23% higher profitability compared to those with disengaged leaders. The research also reveals that companies in the top quartile for employee engagement achieve 10% higher customer ratings and 18% higher productivity.


What Makes the Difference?

Great managers create a ripple effect throughout their teams:

·        Boost employee engagement - Engaged workers are 31% more productive and have 37% better sales performance

·        Reduce turnover costs - Good managers cut voluntary turnover by up to 40%

·        Improve customer satisfaction - Teams with strong leadership see 12% better customer metrics

·        Drive innovation - Engaged employees are 3x more likely to contribute new ideas


The research is clear: investing in manager development isn't just good for morale—it's essential for financial success.

In most organizations, the instinct is to add —more goals, more projects, more meetings. But as Juliet Funt, founder of the Juliet Funt Group, teaches in her Strategic Choice process, real leadership strength lies in deciding what to stop doing . Strategic Choice is the intentional narrowing of priorities—cutting away the clutter so teams can focus on what truly drives results. It’s a disciplined act of letting go: saying no to good ideas so there’s room for the great ones. Funt’s approach challenges leaders to pause, think, and create the mental and operational space their people need to perform at their best. By removing unnecessary tasks and misplaced effort, leaders make room for precision, innovation, and real thinking time. This isn’t about doing less—it’s about doing what matters most. When businesses adopt this mindset, they replace overwhelm with clarity and regain control of their time, energy, and outcomes. For small to mid-sized companies, embracing Strategic Choice can transform busyness into focus—and that focus is where sustainable growth begins. Want a quick visual overview?
