-The week on / week off schedule. Switching from 5am -5pm to 5pm-5am shifts every other week is mentally draining and no one should be subject to that.
-Bad office politics and bad overall vibe.
-Management constantly switching up on you.
-The risk of losing your job is always looming overhead unless you're in the "In Crowd"
-No remote work despite perfectly having the ability to do so. If you are working 5pm-5am you barely saw anyone else - there was no reason to make people working over night going in.
