Legal Question in Discrimination Law in Kansas

Nation of origin, although seldom plead, is a prohibited criteria for discriminatory employment action, like race or gender. If your grandfather's manager is treating hom differently from other employees because of he was born outside the US, it might be actionable discrimination.

Your grandfther should bring this mistreatment activity to the attention of the owners or higher up supervisors of the Hotel/restaurant company. If they do not adequately investigate and address the mistreatment, yoru grandfther should make a claim with the Equal Employment Opportunity Commission (EEOC) very soon thereafter. You said your grandfather's English is not too good. He might opt to take an advocate with him to report the mistreatment to the higher ups, or make his report in writing. Hopefully, the manager or the company will not retaliate agaisnt him for making the reprot. If they do, that would be an EEOC violation, even if the manager's activity thus far is not.

Not all mistreatment is actionable. If it turns out that this manager is jerk that mistreats most or all of employees, it is not disciminatory. The EEOC does not protect against distaful jerks. jus tthe ones that choose theri victims based upon one of the prohibited criteria (i,e, race, nation of origin, etc.)
