Why don't some companies encourage internal employees to fall in love?

Where there is love, there is marriage. Marriage is the combination of two families, and family combination will bring responsible affection. For example, when recruiting, managers may prefer those who are incompetent but have relatives, because such people need to be assured and reliable. So bad money drives out good money. When newcomers enter the company, the first thing they think of is to find out the relationship between the company, who is the brother-in-law and who is the daughter of the big leader. Such a capable person will have no interest in business and concentrate on complex nepotism. Office romance is inevitable. At the same time, it is difficult to prove, confirm and deny office romance. Even if you find two people in love, what will you do if people claim to have broken up tomorrow? To take a step back, even if there is no office romance, it is easy for colleagues to form good friends, and drinking, traveling and taking a sauna together will also form a very close professional distance relationship.
