Pray-you-don't-get-sick-insurance. Really poor training + onboarding. Even worse "offboarding" if you could call it that. There's no room to be anything but a star here, which you could say about any place but at the least you might get support to find out where you can be a star somewhere else.
Culture of being "nice" but not being kind. For example, telling someone who is struggling that the work looked fine and there was just a few things you'd change, then running to tell their manager about how you're concerned their work is looking really bad, is "nice". Kindness is reaching out to them FIRST instead of letting them find out from their manager or glean what they can off of messages, and walk through their work with them to try to pinpoint a problem. I understand being understaffed and overworked effects peoples' ability to do the right thing towards their colleagues, but I'm telling you that it goes a long way.
I honestly would stay away from here if you're not white, they initially had some good bones of a plan to support BIPOC employees in the beginning but after the acquisition all that flew out the window. Even without that, I think there's a specific brand of Midwestern racism going on here where you're expected to deliver the moon but if you don't they always knew you would suck.
