My job would probably be considered a blue collar job. I program and operate machines, solve problems that occur with them on a regular basis, have pretty much total autonomy in the decisions I make about how to do my work, I get to be creative every single day, most of the time my boss asks me how to do things rather than telling me what to do. Or may tell me that a customer has asked for something, asks me if we can do it, I, for the most part, will say yes, then somehow find a way to do it and I learn new things and skills all the time.

Honestly if my job wasn't like that, I would've left long ago despite the decent pay.
