What exactly happens if you break a three month resignation period? I don’t advocate doing this in generally but as a hypothetical exercise if this person just stopped showing up for work, what exactly could the company do?
In America absolutely nothing happens. He might have some type of agreement where he gets a severance payment upon resignation, that would be forfeited. If I was him, assuming upper management starts yelling or whatever, I would just leave. Stress can kill you, and stressing over a job is absolutely never worth it because if you die today , they'll post a req for your position by the end of business.
It looks like they could probably sort something out, wouldn't be a bad idea to call up any of the old vets who retired to see if they could come down to the office and contract for a week or so.
