Childcare is getting surprisingly expensive...
But I think the huge issue (from the Packers perspective) is the legal liabilities that comes with childcare.
Such what if the person you hire is horrible with the kids? Or does something illegal... I certainly wouldn't want the legal liability of childcare, even if it was a profitable business.
If I was the Packers, I might assist the players setting something up, or finding something, or getting someone else getting a business going, but there is 0% I'd be a middleman and risk the legal liability of it.
The closest I might be willing to get, would be, with all these new spaces the Packers are adding, maybe (ONLY MAYBE) building one that's super duper safe and renting it out to another business, that just so happens to do childcare, and they're taking the legal responsibility.
As far as how big of a problem this is, I'd say that it totally depends on the availability and costs of privately available childcare in the area (which I have no idea of).
But I assume the Packers would help, as long as they don't have to take on the legal liabilities or the actual running of a childcare business.
