HR managers face a tough dilemma when it comes to employee training, education, and development. On the one hand, learning is linked to engagement in the workplace. After all, if employees feel like they are progressing and gaining new skills or knowledge from a job, they will be more likely to work hard and stick around. On the other hand, company leaders always want to know the bottom line—the ROI or other benefits—which can be exceedingly difficult to measure when it comes to employee learning and development.
