Employers are not required to grant preferential treatment to an individual or group on the basis of race, color, disability, religion, sex, national origin, or age, even when there is an imbalance in the workforce (TX Labor Code Sec. 21.113). However, private employers may develop and implement personnel policies that incorporate workforce diversity programs (TX Labor Code Sec. 21.121). In addition, home-rule municipalities may adopt programs designed to increase participation among minority business enterprises in public contracts.
