Management putting pressure on the people without thinking about burn out, no consideration towards the employee whatsoever.
One of many illustrious example, manager told me: "You are working 8 hours a day, I need you on this topic at least half of that time and I mean at least 5 hours." Initially, I thought it was just a "mistake", tried to push back stating half of 8 is 4 not 5, while the reply was essentially that in our team half of 8 is how much my manager says. Terrible.
