I wonder how these hold up, and what the clause “I agree not to cause any other employees to get hired” means in a legal sense. Like, if you and I work at Company A, and you go to Company B and I want to go there because it’s amazing. If you recommend me, is that causal? I have to interview and all that still.

If you leave for a managerial role, can you hire me if I make first contact with your new company? That seems causal, but also easily circumvented.
