Correlation Between English Grammar Comprehension and Job Performance: A Case Study of Furukawa Employees

Abstract

This study examined the correlation between English grammar comprehension and job performance among employees of Furukawa. As English serves as a global medium for communication in professional and industrial contexts, proficiency in grammar is considered a crucial component for effective workplace communication, documentation, and collaboration. Using a descriptive-correlational case study approach, data were gathered through standardized grammar assessments and structured job performance evaluations administered to thirty (30) selected employees. Statistical tools, particularly Pearson’s r correlation, were utilized to determine the strength and significance of the relationship between grammar comprehension and job performance. Findings revealed that employees with higher levels of grammar comprehension demonstrated significantly stronger job performance, particularly in tasks involving report writing, email correspondence, and coordination with clients. Moreover, results indicated a statistically significant relationship between English grammar proficiency and job performance, with grammar comprehension emerging as a stronger predictor of workplace effectiveness. The study highlights the importance of enhancing employees’ language proficiency as a means of improving organizational productivity and competitiveness. It is recommended that companies implement targeted English grammar training programs to support employees’ professional growth and communication efficiency.
