Hey guys, so there's this guy who works with me and gets on my nerves everytime. He never does his job and the whole team keeps getting blamed for his laziness. Everytime I do something, he smirks at me and says something in the line of "Oh, that was my job. Thanks for making my life easier" and that sort of bullshit. Being the son of one of the important figures of the company, he thinks he can do whatever he wants. How would you guys handle him?
