I wouldn't lie about a crisis, but it's business. It's not unheard of to take a better offer and offer to work as a consultant at the previous employer.
The lying about the crisis is the part that I was referencing was shady. Working as a consultant for a previous employer is completely acceptable and provides mutual benefit.
Crisis story can be looked at as advertising or setting the table. You leave your old company with a reason and everyone feels better. Your image is safe and your backstory.
If anyone feels like this is dishonest what do you tell your new employer about why you are truly leaving the old position. Do you tell them the owner was rude and you told him off or do you say you left because of a bad personality fit? You are not lying but perhaps a little dishonest. You can have a personal crisis and that could be the new job.

I'm sorry, it's simply bald-faced lying. If I found out any of my hires had done this, I'd fire them.

I rarely need to tell them anything, but if they ask, I say "I'm seeking new challenges". It's not a lie, and it avoids potentially bad-mouthing prior employers. But I'll be honest here -- it's only happened twice in my career that I left a job because of something bad about the job.
Seeking new challenges is not being honest either. But it makes you see the person in a different light compared to the other more accurate version. That's what is happening with the personal crisis story.
Would you fire that same person if you discover a year later new challenges meant hated old boss and told them off?
Just curious are the positions you manage that easy to fill that you can fire at random?
If someone I knew was fired for that reason a lawsuit would be very likely. The manager would be let go after they lost cost the company so much money. I'm not in the US so I understand the rules might be different but usually you can't fire someone because they broke your personal moral code.
