Why Does Your Boss Overreact to Some Things and Ignore Others?
Humans are biologically wired to protect status and survival before anything else, your boss included. They snap at some things and shrug off others because of: 1) self-preservation instinct, they're guarding their own job before yours 2) loss aversion, they feel the risk of something going wrong way harder than the upside of it going right 3) reputation management, they're managing how they look to whoever's above them, not just how the shift runs. You're not reading a mood. You're reading a threat map.
