My dad works in a warehouse for a small company. He is in his 60s and very fit with good health. The other people there are desk workers and they are Millennials with zero respect for older people and they talk shit about my dad and the other old guys there. The younger guys who are very weak and skinny will complain to my dad that he is not working hard enough. My dad had quit one month because they refused to give him a raise and when he left they couldn't find anyone to replace him so they had 7 of the desk workers to do his single job. They called him back and gave him a raise, but they still treat him like dirt. I am so angry because I know how hard my dad works and he is old so he can't just get a decent paying job elsewhere. I want to know what I can do for vengeance. He is not in danger of being fired and would welcome it, so I want to know what I can do. I can't stand my dad being taken advantage like this. I am extremely angry.
