Is it illegal to ask employees to be single in company recruitment?

The company requires job seekers to be single. Is it illegal to ask job seekers about their height and weight? It is not illegal to require the height and weight of job seekers, but it is not necessarily related to the "inherent requirements of work" to require job seekers to be single. In other words, assistant job seekers can complete it regardless of whether they are single or not. The company requires job seekers to be single, which constitutes employment discrimination, discriminates against job seekers and infringes on their equal employment rights. The fact that the company requires employees to be single in recruitment has caused an uproar on the Internet. Netizens are mainly divided into two factions. Look at their messages. Some netizens, from the company's point of view, think that who to recruit is the company's own freedom. Ms. Chen reported that this company belongs to "the dog meddles with the mouse". Some people go deeper and think that Ms. Chen's practice is actually self-interested behavior that harms women's employment opportunities. Most netizens think that there is no problem with the company's practice, because if there is no recruitment requirement, how can the company operate? Of course, some people understand Ms. Chen and think that it is a bad habit for this company to require job seekers to be single, which needs to be banned as soon as possible. Whether a job seeker is qualified for the job depends on his ability, not his appearance and marital status. This kind of thing is reasonable, but according to our current labor law, Ms. Chen's behavior should be encouraged. Only when there are more and more serious people like Ms. Chen Can can the legitimate rights and interests of job seekers be better protected.
