This study examined the impact of collaborative strategy on employee performance in oil-producing companies in Port Harcourt. Using a cross-sectional survey design, primary data were collected via structured questionnaires administered to employees across five oil firms. From a population of 345, a sample size of 181 was selected based on Krejcie and Morgan’s table. The reliability of the instrument was confirmed with Cronbach’s alpha coefficients exceeding the 0.70 benchmark. Data analysis involved descriptive statistics and Pearson’s correlation. Findings indicate a significant positive relationship between collaboration and employee performance. The study concludes that conflicts and disagreements are inevitable but can be effectively managed through collaborative strategies to enhance teamwork and collective organizational goals. It is recommended that management proactively identify and resolve conflicts early by fostering collaboration, which serves as a vital tool for dispute resolution, improved productivity, and achieving corporate objectives in the oil sector
