It is an unfair practice for any employer, employment agency, labor union, or other person to:

(1) Refuse to hire, discharge, bar from employment, or otherwise discriminate against an able worker with a disability or because of the use of a trained dog guide or service animal by an able worker with a disability; or

(2) Fail or refuse to make reasonable accommodation for an able worker with a disability or the use of a trained dog guide or service animal by an able worker with a disability, unless to do so would impose an undue hardship (please see WAC 162-22-065 and 162-22-075); or

(3) Refuse to hire or otherwise discriminate against an able worker with a disability because the employer would be subject to the requirements of this chapter if the person were hired, promoted, etc.
