WASHINGTON — When Kenni Miller started as a shift manager in his local Sheetz convenience store in Altoona, Pennsylvania, he felt something that he rarely had as a Black man in the workplace. He felt trusted. He felt appreciated. When he was fired a few weeks later, in the summer of 2020 after a background check, Miller, then 27, was devastated. A nonviolent, felony drug conviction from his teenage years had never caused him to be denied a job before. And he had already proved he could do the work.
