If "the Employee is Part of the Product" Then Boosting Investment in Employee Engagement Can Pay Off

Even if a “leaner” approach to employee staffing might make sense for some firms, at some times, there also is an argument to be made that for “high touch” customer experience” businesses, investing more in workers can pay off. 

Better treatment, training, scheduling, and support raise employee commitment, which tends to improve service quality, product knowledge, and consistency. 

That perhaps matters most in businesses where the employee is part of the product, such as retail, hospitality, call centers and healthcare. 

Even seemingly less important contributors such as stable scheduling can produce results, some studies find.

The best-supported pattern is not “pay more and sales automatically rise,” but rather “invest more intelligently in the employee experience and customer experience often improves enough to more than offset the cost.”

In customer-experience businesses, spending more on employees can be a growth investment, especially when that spending improves retention, skill, scheduling stability, and commitment, says Apollo Technical.  

Research shows that when customer-facing employees become more experienced, stable, and engaged, customer experience improves and sales can rise materially.

Employee engagement refers to how connected workers feel to your business; their sense of belonging and purpose in their role; their alignment with your company values; and how appreciated they feel by colleagues and superiors, Apollo Technical says. 

One might argue this matters less in some industries or businesses. It arguably matters much more in situations with a “high touch” people-dealing-with-people character. 

There, a correlation between how employees feel and how they treat customers arguably matters. 

If employees are highly engaged, they are more likely to provide positive customer experiences and build strong relationships with customers

According to Gallup, there is a direct correlation between engagement at work and organizational outcomes.

Gallup looked at 736 research studies across 347 organizations in 53 industries, with employees in 90 countries. In total, Gallup studied 183,806 business and work units that included 3,354,784 employees.

It calculated the business and work-unit-level relationship between employee engagement and performance outcomes, studying 11 outcomes (including some quantifiable accounting outcomes and harder-to-quantify attitudes:

• customer loyalty/engagement

• profitability

• productivity

• turnover

• safety incidents

• absenteeism

• shrinkage

• patient safety incidents

• quality (defects)

• wellbeing

• organizational citizenship.

Across companies, business or work units scoring in the top half on employee engagement more than double their odds of success compared with those in the bottom half, Gallup says.  

Those at the 99th percentile have nearly five times the success rate of those at the first percentile.

The median percent differences in outcomes between top-quartile and bottom-quartile outcomes seem significant.

• 10% in customer loyalty/engagement

• 23% in profitability

• 18% in productivity (sales)

• 14% in productivity (production records and evaluations)

• 21% in turnover for high-turnover organizations (those with more than 40% annualized turnover)

• 51% in turnover for low-turnover organizations (those with 40% or lower annualized turnover)

• 63% in safety incidents (accidents)

• 78% in absenteeism

• 28% in shrinkage (theft)

• 58% in patient safety incidents (mortality and falls)

• 32% in quality (defects)

• 70% in wellbeing (thriving employees)

• 22% in organizational citizenship (participation)

The point might be that a focus on cost discipline often matters, but the the key is to evaluate labor as a value-creating input in service-heavy businesses, not just as a margin drag. 

The question becomes whether additional spending raises tenure, commitment, skill, and consistency enough to lift conversion, basket size, repeat visits, or retention. In the right business model, that tradeoff can produce a genuine turnaround rather than a cost overrun.

On the other hand, there is a meaningful body of evidence showing that employee satisfaction, by itself, does not reliably translate into better business outcomes.

Gallup emphasizes that keeping employees “happy” is not the same as building engagement. 

Satisfaction may reflect how people feel, while outcomes depend on whether people actually change behavior in ways customers notice, one study suggests.  

A satisfied employee can still be poorly trained, misaligned with the job, or working in a process that prevents good service, so satisfaction alone may not move revenue, productivity, or retention. 

In other cases, a positive effect may exist only under specific conditions, such as high empathy, strong customer trust, or better sales management. 

So investing in employee engagement, in high touch businesses, might be viewed as a necessary, if not sufficient, step to produce better outcomes. 

Workers have to buy in, and reflect that commitment in service to customers.
