The transport companies in Anambah appeared to be making recruitment based on gender, religious and tribal bias. This study is propelled to determine the extent of relationship existing between workforce characteristics and employee performances of the selected transport companies in Anambah state. The work was anchored on Social-categorization theory associated with the work of Turner (1987). By the use of structured questionnaires, disseminated by face to face contact, the paper surveyed four transport companies with cumulative staff strength of four hundred and sixteen. Tables and regression analysis were used for data presentations and analysis respectively. Hypothesis was tested at 5% level of significance. The study revealed that a positive correlation exists between the dependent variable (employee commitment) and the independent variable (biological construct; tribe, Gender, Age and Religion) with a correlation coefficient of .972. The result also revealed that a 94% change in the dependent variable is explained by changes in the independent variable as shown by the coefficient of determination (R Square = .944). Sequel to this, the study concluded that efficient and effective workforce composition has the ability of positively affecting the performance of the employees. It was therefore recommended that the studied firms should ensure that their workforces possess appropriate characteristics to enable them attain high performance and that no bias or discrimination should be enshrined in the recruitment processes of the studied firm so as to ensure that the right kind of employees with the requisite characteristics are employed.
