I predict him pulling an illegal stunt and getting off scot-free because he's wealthy and has aligned himself with the christofascist party that doesn't support the rule being used against its own.
That's the part of the point of the comment you are replying to. The fines are neither a deterrent nor an inconvenience to those wealthy enough to cover the cost. They use their money, power, and influence to continue to violate law without any other consequences other than pulling out their checkbook. The fines are meaningless to people that wealthy.
I predict he fires everyone and hires people on H1B visas using a contractor.
Edit: Even if the NLRB forces him to recognize the union he can just pull a Starbucks and refuse to negotiate. Meanwhile he can drag out every wrongful termination suite and still hire people on H1B visas and save who knows how much doing so.
