The Delaware Discrimination in Employment Act (DDEA) prohibits employers from discriminating against individuals because of their religion in hiring, firing, and other terms and conditions of employment. It covers employers with 4 or more employees, including state and local governments. It also applies to employment agencies and to labor organizations.

Under the DDEA:

• Employers may not treat employees or applicants less - or more - favorably because of their religious beliefs or practices. For example, an employer may not refuse to hire individuals of a certain religion, may not impose stricter promotion requirements for persons of a certain religion, and may not impose more or different work requirements on an employee because of that employee's religious beliefs or practices.
• Employees cannot be forced to participate -- or not participate -- in a religious activity as a condition of employment.
• Employers must reasonably accommodate employees' sincerely held religious beliefs or practices unless doing so would impose an undue hardship on the employer. A reasonable religious accommodation is any adjustment to the work environment that will allow the employee to practice his religion. Flexible scheduling, voluntary substitutions or swaps, job reassignments and lateral transfers and modifying workplace practices, policies and/or procedures are examples of how an employer might accommodate an employee's religious beliefs.
• An employer is not required to accommodate an employee's religious beliefs and practices if doing so would impose an undue hardship on the employer's legitimate business interests. An employer can show undue hardship if accommodating an employee's religious practices requires more than ordinary administrative costs, diminishes efficiency in other jobs, infringes on other employees' job rights or benefits, impairs workplace safety, causes co-workers to carry the accommodated employee's share of potentially hazardous or burdensome work, or if the proposed accommodation conflicts with another law or regulation.
• Employers must permit employees to engage in religious expression if employees are permitted to engage in other personal expression at work, unless the religious expression would impose an unde hardship on the employer. Therefore, an employer may not place more restrictions on religious expression than on other forms of expression that have a comparable effect on workplace efficiency.
• Employers must take steps to prevent religious harassment of their employees. An employer can reduce the chance that employees will engage unlawful religious harassment by implementing an anti-harassment policy and having an effective procedure for reporting, investigating and correcting harassing conduct.

It is also unlawful to retaliate against an individual for opposing employment practices that discriminate based on religion or for filing a discrimination charge, testifying, or participating in any way in an investigation, proceeding, or litigation under the DDEA.
