A reorg or a team being dissolved is, in origin, a work event. But when identity is staked on the role, the same event arrives as an event about your existence. This post breaks that structure into three symptoms and sho

A junior engineer's anxiety comes from position, not personality. It is the layer most often named as replaceable, the layer with the least evidence behind it, and the layer with the most people to compare against. This
