When the boss asks you into the corner office and begins the conversation with "How do you like working here?" it means your job could be on the line. 
Then if you are asked to "let go" of something, it means the boss would like you to stop, or you could get fired. 
Finally, asking for loyalty means, "You're OK with this, right?"
When the mafia boss says: "You have a nice family. I hope you can solve this problem. Capiche?" That is a threat.
