I don’t have kids either, but to me it’s logical, that that this has to be taken to account. I mean, those are people who are dependent on the situation, it’s not like they could do anything on their own. I’m happy, that at least this is something, where humanity comes into play. And again: I don’t have children and I don’t want them in the future.
And like I said, there are also other points, like age, or how long the people are working for the company.
What would be your points, to decide if someone has to be fired? And no, firing no one at all is not an option in this scenario ;)
