Politics is a when a company like Caterpillar spends a year trying to acquire GPU's for their autonomous vehicle teams, because they have 20 security and project managers that want to assert themselves in every conversation to get promoted, to get to senior leadership positions, while the company looses out to Chinese competitors they were ahead of.

Politics is also when middle managers and 2 engineers conspire to steal a coworkers work to get promoted and move up the silicon valley startup ladder, so that the company has to come back a year later to bring back the original engineer, because none of these people were capable.

If you haven't seen politics you might have been either blessed or didn't want to see it, but for every 1 company I worked with that was efficient I worked with 4 that were not.
