Shortly, don’t talk about ethos, I have seen 50 colleagues destroyed while I was undergoing training, and was too busy sorting out my own life and career. I have also witnessed single cases of fellow colleagues dismissed for petty reasons, but true to your arguments I assumed that it was entirely their fault. Then one day it was my turn, and in a way I got what I deserved, because I denied truth and morality for too long.
If you choose to keep your mouth shut, then fine, if you find the company culture acceptable, then again that’s fine, because it’s horses for courses, but your disparaging comments about those that suffered under this system are very offensive and I doubt that even you would find your contributions to this thread tenable when confronted with the family of our young colleague who tragically died during the recent industrial conflict.
You might even find that truth is NOT a question of personal taste.
