Processes are often chaotic or broken, and it is very difficult to fix due to bureaucracy; any decision requires consensus among 30 people on 10 levels. 99% of your professional well-being depends on your line manager. If you have issues with them, you have NOWHERE to go. HRs will be the first to tell your boss you reached out flagging problems. HRs always support the manager, so no one really trusts them despite the public image of the company caring for employees' well-being. After all, it is still a traditional corporation, just with more slogans about mental health written on the banners.
