Legally

"How am I going to do that? Easy, by getting your arse fired and making sure no one else will ever hire you again."

Craig reels back as if hit. This took him by surprise. You have him on the ropes now and he takes a step back as his mind tries to find a way out. "What? How?"

"Easy. I go to HR, make a complaint about bullying. I've got enough stories to fill a book. And I'm sure there's plenty of other people who would back me up with their own version of events. You're not as popular around here as you think you are." You pause for a moment and pull one last card. It's a bluff but he doesn't know that and right now, you could be the worst liar in the world and he wouldn't notice. "Besides, I've got proof. You think I'm stupid? I've recorded at least half a dozen times you've 'just been playing around' and bullied myself or others!"

Craig licks his lips, his eyes shifting back and forth. You can see him almost bouncing on the balls of his feet. "Wh-what do you want?"

"Easy. Leave me alone. And leave everyone else alone as well. No more bullying. No more teasing. No more threats or harrassment. Clear?"

"Uh-huh"

"Now Craig, fuck off."

Craig turns and practically scurries back to his desk with his tail between his legs. As he does so, you almost collapse. Your legs are jelly and your breath comes in short, sharp gasps. What the hell came over me? you wonder to yourself. You sink into your chair and look up at Bianca. She is practically beaming at you, her smile stretching joyfully across her face and her eyes glowing. "That was amazing!"

Whatever it was that came over, you're pretty sure it was a good thing.
