You don't think adultery should be criminalized. But do you think something should be done? If so, what?
I dunno. Social censure? People who know the full facts of the matter know that he done her wrong, or she done him wrong. Or everybody did everybody wrong. Or, under the circumstances, it wasn't as wrong for her to do that as you might think. Or, they had an open marriage, and it wasn't wrong at all.
For example, would adultery be a basis for divorce? If so, should it be a factor in determining division of property, child custody, etc.?
Maybe?
Could it be a basis for business action? For example, would it be moral to make certain jobs contingent upon maintaining a standard
I think it's weird to ask if it would be
moral for a company to do something like that. It might be legal for them to do it, or even wise for them to do it. But I don't see it as a moral act itself.
I signed a contract at a religious school that declared that if I perpetrated 'acts of
moral turpitude', I would be subject to dismissal. I can imagine if a person were publicly outed as a baked potato fetishist, it could bring ridicule on the employer that they'd prefer not to have. But that's only because the fetishist was found out in public. It seems the morality or immorality of the acts themselves are beside the point. I don't see it as a moral act for an employer to say "If you do anything weird, for Krishna's sake, don't get caught at it.'
and so adultery would justify termination of employment?
Unless it affected or potentially affected their work (like sleeping with a coworker or a subordinate), I don't see it as a fire-able offense.
Could it be a basis for refusing services?
I don't think so.
Could it be a basis for social action? Removal from membership in an organization?
It could be.
Bottom line, it seems you're implying moral power should have a limit.
I dunno. Morality is the manner of deciding that things are either right or wrong (or neutral or blameless or 'mostly wrong' or 'the best you could do given the choices at hand'). I'm not restricting that power. People can judge all they want (nobody can stop them) using their moral faculties.
I'm placing limits on legal power to enforce morality. It's immoral to be a jerk, but not a crime.
