I work in a factory, and the potential to move up to shift lead is all but given to me by my peers. Ive had several bosses and colleagues (who's opinions and world views align with us) tell me I need to become the lead. The guy I would be inheriting this role from even says I'm the best fit.
However I ain't trying to be some class traitor. I do like the thing we produce, it's been a part of my life for my entire conscious existence. I'm a lucky sucker who followed their passion and while I'm a wage slave, seeing people, even if it is the upper class, deriving happiness from the things I make make me care about the things I produce. I do want to use this position to make the product and the workers lives better. Management already understands I side with labor more often than not.
I am really good at what I do and I have tons of issues believing in myself, but it's hard to ignore the world telling you you got to do this.
I don't think there's virtue in your relation to production (i.e. in being a prole). Virtue comes from what you do in your position. Being a lead/foreman/whatever isn't being a class traitor, being a shitty one who is cruel to their subordinates and licks the bosses' boots is.
