Low pay and shitty corporate conduct doesn’t exactly encourage the most compassionate people to apply, sadly

Jeez, I was hoping to click the link and find that it was an old article because I know I saw this exact situation in another article a couple years ago :(

Part of the problem is that when you work with children there's always a moment that makes you consider it. When 3 or 4 are going off on one at the same time there's just a second where it comes to mind before you dismiss it as unreasonable.
When you're low paid and have shitty management those times tend to be a lot more common and you have fewer tools to deal with them. Eventually, when you run out of reasonable alternatives, it starts to look a lot less unreasonable.
