So you're an employer, and half of the population has a chance to have to abandon work to bring new life into the world and also will thereafter be responsible for caring for that new life, in such a devoted way that they can't really do quite as much for your business anymore. You know this is a possibility for that portion of people you employ. They therefore are most likely given opportunity to take parental leave, meaning you must ensure they can return to work when ready, with the same pay and similar work, while you have to find a person or people to fill in that labor gap during said leave. Then you have to figure out what to do with that other, new employee. More than likely you may have had to pay theat older employee while they provided little to nothing to your micro-managed business that has been your primary focus for some time, and you yourself are probably making your reproductive plans to make the least effect on your business. The other person can make you no such guarantee and really to expect that would be insane. On top of that if you provide a subsidized or free health insurance plan to that employee, you're paying for their hospital bills from when they had to produce a new life form from their own body. Regardless of if they even take any form of parental leave available to them, they are more likely than the other half of the population to leave the workforce altogether and be full-time parents since it's very socially acceptable and a popular choice for this half and not the other, leaving you with a position to fill that is as big as you, the employer, gave your old employee.

There is another half of the population that, while they can still be parents, are not allotted a parental leave of any kind. In fact, in the event they become a parent they may even push for bigger, more important positions in the workplace and while they may expect raises and try for positions that make you rely on them more, they will not have an option given by law to allow them to go home and raise their children while still receiving pay or expecting to return to their job where they left off. Instead, they will pursue their career in your business uninterrupted and will continuously provide work. They might even demand to be given an insane workload and become your trusty beast of burden in the event their partner decides to stay out of work and that employee of yours is now feeding three mouths alone.

Who do you want to hire? Who do you want to promote, rely on, and invest in? It's quite simple, and to a world where money runs everything, it's a scale tipped over.

However, introduce a genderless law where only one or both parents can choose a parental leave, regardless of what's between their legs, and the employers' decision on who to choose between is irrelevant, the same risk-reward exists and it's just up to men and women to work the same.

Paternity leave is a right for men, and it will make for a better world. There's plenty of men's rights issues where the resolution would mean a great benefit for both genders, but unfortunately we're just a bunch of evil misogynists according to organized feminism.
