***What to do about my coworkers?***?

I"ll start out by saying I love my job. Even though it is a minimum wage job getting me through college (I'm 18), I still like it. I work in a manufacturing shop and it beats working fast food, so I'm extremely thankful.

However I cannot stand most of my coworkers. All day they want to gossip about each other behind each others backs and screw around on the job. These are 20 - 40 year old men. At lunch time they all have their faces in their phones giggling at funny videos on youtube while smoking cigarette's like a chimney when the building clearly says "No Smoking within 20 feet of the building." Cursing their tools and cursing each other all day long. I probably hear 1,000 swear words a day just working around these guys. No joke.

Just yesterday, some guy working next to me was singing Ole Ole Ole Ole for a solid ten minutes.

I know they've started rumors about me, being the new guy and all, because some have gotten back to me. I really could care less. I just ignore each and every one of them unless it pertains to work. I'm not here to make friends, I'm here to work my butt off and get paid for what I do.

It's not that I am shy, I just can't find any common ground with any of them. When something needs done or when I need to stand my ground then I'll put my foot down, otherwise I'm pretty much silent.

Is this bad what I am doing? Is there anything else I should do? Thanks!
