Overtime is well compensated, colleagues from other departments are fairly easy to get along with, and the new office is bright and comfortable

Severe office politics. The department that was supposed to be innovative saw nearly an uncountable number of people leave within a year—almost enough to count on both hands, with most of them in positions like mine. Before and after submitting their resignations, everyone says you are highly capable, but after you resign, a certain manager immediately replies on the approval form that everything is fine and that they have worked hard to make adjustments, and that the departing employee lacks ability. Only after leaving did I realize that perhaps 90% of what a certain manager had been saying behind people's backs was untrue.

An expert in managing upward may be a nightmare for newcomers, because the person who repeatedly says they want to help ultimately assigns a somewhat more senior new hire—who is completely unwilling to communicate and, when communication fails, goes straight to their good friend (a certain manager)—to micromanage them.

After only two months on the job, I was criticized by a certain manager for having too little work. But when I asked, it turned out they had not actually thought about assigning any new work to me. The fact is that my original workload was already excessive.
