Workplace Religious Freedom Act of 2003 - Amends the the Civil Rights Act of 1964 regarding religious observance in the workplace to declare that for an employer's accommodation of an employee's religious observance or practice to be considered reasonable, it must remove the conflict between employment requirements and the employee's religious observance or practice.
Deems as an unlawful employment practice an employer's refusal to permit an employee to use leave of general usage to remove the conflict solely because the leave will be used to accommodate the religious observance or practice of the employee.
