Delaware is an employmentatwill state, which means that, absent an employment contract (or collective bargaining agreement), which provides otherwise, an employer can discharge an employee for any reason, or no reason, with or without notice, as long as the discharge does not violate a law (such as the employment discrimination laws).
Have you been discriminated against by a potential or current employer -- as a job applicant or current employee? To best protect your legal rights you should discuss your situation with an employment lawyer. Meet with a local employment attorney sooner rather than later to protect your rights.
