The key distinction between NPS (Net Promoter Score) and eNPS (Employee Net Promoter Score) exists in their survey target. Customer loyalty and satisfaction levels in NPS are assessed through customer survey responses about their likelihood to recommend company products or services. eNPS evaluates employee satisfaction by determining how likely workers are to recommend their employer to potential job-seekers.
Employee NPS measures engagement and internal company culture through calculations similar to those used for NPS.
