The focus of this study was derived from staggering attrition rates that it calls centers year over year. At times call centers post-COVID-19 pandemic saw attrition rates fluctuating between 30%-50%. With any job there are challenges that are faced. These attrition rates stand 28%-40% higher than the United States 2023 national attrition rates of 3.8% based on the Bureau of Labor statistics. This proposes the question, "Why are call centers facing devastatingly high attrition rates?" From this the study was designed to look at the onboarding experience of adult learners, their emotional state, how they perform in training versus the performance once they take live phone calls post training. The three data sets collected from a large group training were the emotional status of an adult learner during training, assessments given throughout an 8--10-week training/onboarding, and the performance of adult learners once they started taking live calls once they have exited training. These data sets were measured against one another to find correlation and commonalities in performance versus emotions. Based on results of the two-tailed t-Tests it was proven that the emotional scores of adult learners coupled with their performance pre- and post-training have a direct correlation. This can be specifically seen as significant because the P value results derived were far below .05 representing that there was statistical significance across data sets. The results being that if adult learners are feeling more confident and happier than they in fact show better results in performance. And if adult learners have high stress and anxiety then they in face will have lower score or struggle more when they are performing on the job. From these results the null hypotheses were both rejected while the alternate hypotheses were rejected. The conclusion of this study is that the onboarding and training process can be predicting factors to an adult learner's performance and longevity with a company. By considering these factors when companies run training, they may be able to start to battle high attrition through giving better support to new hires when they are learning their roles.
