Therefore, one of the factors to consider is the job performance and staff turnover of a company for better growth. The objective of the research was to determine the relationship between staff turnover and job performance of janitors and cleaning workers in a SME (Small and Medium-Sized Enterprise). The methodology had a quantitative approach, with a non-experimental design, cross-sectional and correlational level. The sample consisted of 120 workers, including janitors and cleaning workers to whom a survey was applied to collect information. The results obtained showed a value p0.05 therefore, the null hypothesis is rejected what's more, a moderate positive correlation (r = 0.359) was determined between staff turnover and job performance likewise, a moderate positive correlation (r = 0.380) between voluntary turnover and job performance finally, a moderate positive correlation (r = 0.352) between involuntary turnover and job performance. It was concluded that there is a relationship between staff turnover and job performance of janitors and cleaning workers in the MSE company.
