Her personal opinion shouldn't matter if she does her job well (and doesn't let it interfer with her job)  Japanese courts agree:  Asahikawa District Court on Dec. 27, 1989, ruled against a company (Hankiko Setsubi) that fired a female employee but not a male one after discovering the two were committing adultery. Management reasoned that even if it does not interfere with work, “adultery adversely affects the company’s moral order, hurts coworkers’ motivation, and makes the president lose face.” While acknowledging that the woman’s actions were illegal and immoral, the court said that only specific damage to the running of the company constitutes hurting the workers’ moral order or motivation, a condition not met in this case. Thus judicial precedent prohibits disciplinary action for problematic personal behavior that has no connection with work duties. Meanwhile, only if such personal actions severely damage a company’s overall reputation can they be considered to have seriously damaged the company’s moral order.
