Just posting a photo of someone else’s child on your Facebook page without permission is wrong. Maybe if you’re in a public place and there are children a distance a way, that’s one thing. Many times, though, when people are closer, they can see someone is about to take a photo and get themselves and their children out of the way if they don’t want to be photographed. But this? That’s just wrong to begin with.
I agree, but that would be a matter for the parents to sort out. Not a firing offense in my opinion unless he used company resources to post the pic or posted it to a company page.
