The managers here are each more sinister than the last, skilled at turning subordinates against one another to consolidate their own positions. Most people cannot see through it and only complain about their colleagues; some who want to curry favor with their superiors even help frame coworkers. The few who recognize the root of the problem either cannot endure it or are singled out and bullied terribly by their managers.
This is no longer a company where you can seek stable career development. The moment you are hired, a great deal of office politics awaits you. Value your life—stay away from PChome.
