(1) It shall be unlawful for an employer or any other person to interfere with, restrain, or deny the exercise of, or the attempt to exercise, any right protected under this Chapter.

(3) It shall be unlawful for an employer's absence control policy to count sick time taken under this Chapter as an absence that may lead to or result in discipline, discharge, demotion, suspension, or any other adverse action; provided, however, that nothing in this subsection shall prevent an employer from taking an action against an employee who uses sick time under this Chapter for purposes other than those enumerated in § 9-4105(1).
(4) Protections of this Section shall apply to any person who mistakenly but in good faith alleges violations of this Chapter.

(b) informs any person about an employer's alleged violation of this Chapter;
(c) cooperates with the Agency or other persons in the investigation or prosecution of any alleged violation of this Chapter; or
(d) opposes any policy, practice, or act that is unlawful under this Chapter.
