Why would anybody’s spouse/partner be the business of their employer? It’s you who’s applying for the job not them. It’s a bizarre question to ask – unless they were actually using it as a way to determine sexuality. I think that not only should the company be prosecuted, but the person who sacked her too, so I hope they DO pass it to the police.
In the related article, the group says that they asked her if she and her spouse were involved in politics, the basis of the “lie.” Understandable as they would want to avoid a conflict of interest. Although they did stop as soon as she was hired.
