Honorable term co-opted by corporate douches to pump up poorly paid 'associates' or other low-wage workers. This mis-use of the term devalues real heros by referring to anyone who is doing what the corporate douche wants done at the moment as a hero. A real hero is someone who risks their own wellbeing to save another putting themselves in mortal peril.
Yeah, I'm gonna need you to come in Saturday and clean out this grease trap. Thanks hero!
