Svantaggi
The primary source of toxicity is the CEO, who maintains control through public humiliation and aggressive "dressing downs." No one is safe from these outbursts, but he is particularly hostile toward women, frequently subjecting them to openly dismissive treatment that would be unacceptable in any professional setting. He uses technical meetings and public forums to belittle individuals, shouting down anyone who offers a different perspective or attempts to uphold professional standards. It is a culture of intimidation where "leadership" is synonymous with bullying.
Because the CEO is so volatile, the management layer has devolved into a collection of "minions" focused entirely on survival and internal politics. There is no psychological safety, which has created a climate of surveillance where backstabbing is the primary way to gain "pull." Managers are more interested in disparaging their colleagues to stay in the CEO's good graces than they are in shipping quality products or supporting their teams.
