Effective workplace communication is pivotal in enhancing employee performance, particularly in today's global business environment characterized by diversity and remote work dynamics. This study aimed to examine the role of workplace communication on employee performance within Tanzania Electric Supply Company Limited (TANESCO), focusing on how communication influences job correctness, decision-making, planning, and overall employee productivity. The study utilized a descriptive research design to collect data. A total of 36 participants were sampled using simple random. Data were gathered through questionnaires and analyzed using SPSS for quantitative data insights. The findings indicate a significant correlation between effective communication and enhanced employee performance. Specifically, open communication with supervisors was strongly linked to increased job correctness and performance (mean = 4.81). Communication was also found to facilitate decision-making and planning (mean = 3.53), and there was a recognized relationship between effective communication and overall employee performance (mean = 3.97). However, the traditional top-down communication approach was noted, with a mean score of 3.65, suggesting areas for improvement in adopting more inclusive communication practices. The study confirms the critical role of effective workplace communication in enhancing employee performance at TANESCO. Open and transparent communication, particularly with supervisors, significantly contributes to job accuracy and employee productivity. The study recommends that TANESCO implements structured programs to foster open dialogue, develops comprehensive communication strategies that balance hierarchical and inclusive approaches, and invests in regular training and assessment of communication practices. Additionally, adopting an 'open door' policy and engaging in active listening are suggested to enhance the communication framework within the organization.
