A more common scenario is the defensive team commits an offsides penalty. This is essentially a free play for the offense since they can take the penalty if anything goes wrong, but if they're able to advance the ball a significant amount, they can decline the penalty.
A slight change of ordering makes your point. Team A drops back to pass and holds a Team B player going towards Team A QB. The QB then throws an interception. In that scenario, Team B would decline the holding penalty, upholding the interception.
Regardless, your second example, of the offense committing holding and the defense declining due to an interception is legit. That happens occasionally.
Edit: I think we just took what was more important for the OPs point differently. I took the point as a penalty occurred, not a specific one. And you see it as "how could holding have happened". Which, if we are being pedantic, also wouldn't happen in the scenario you described. If it was called holding, it would have had to occur before the pass, making it not OPI. =).
It is clearly unlawful, but is it criminally unlawful?
Steal a chocolate bar? Jail. Poaching in the kings forest? Death. Caught with drugs without a lawyer? Jail and possible death depending on the jail conditions
Manipulate an election via gerrymandering or lose a million peoples life savings in crooked finance deals? Dumping dangerous chemicals in the local river/lake? Editorial in that weeks paper about how that person should feel bad, plus a bonus
Well I am not a lawyer. But some searching suggests interference violates Section 7 or Section 8 of the NLRB. The NLRB website [0] appears to be down for me at the moment so I can't look up exact info though.
Edit: the site is still sorta spotty but sometimes works.

Companies should play fair or face the punishment. If employees truly don't want a union then don't interfere with their vote.
I think that's hyperbole and could be left at the second half of your sentence:
> Until ... the employer stops breaking the rules.
However, I also think that simply having another election isn't sufficient. I honestly believe that interference like this is clearly unlawful and should be criminally punished as such.
