Biggest one I see especially in software engineering is co-workers and managers losing patience or getting frustrated when you ask them questions.

Ppl usually don’t leave a company they leave bad management, and that’s usually:

They break promises, saying whatever motivates people in the moment but rarely following through. A common example is promising promotions or raises that never actually happen.

They create fear, relying on intimidation instead of inspiration. Employees become afraid to take risks or speak up because they worry about retaliation.

They lack transparency, keeping people in the dark and causing unnecessary confusion. For instance, they may announce important decisions at the last minute, leaving everyone scrambling.

They micromanage, showing little trust in their team and trying to control even the smallest details. A typical example is requiring approval for trivial things like wording in emails.

They gaslight employees, denying reality and making people question their own experiences. A manager might claim, “I never told you that,” even when there’s clear proof they did.

They dismiss feedback, shutting down honest input and sometimes even punishing those who speak up. Some will publicly embarrass someone who challenges them or proposes a different idea.

They burn people out, disregarding employee well-being and expecting constant availability. This includes sending midnight emails and demanding immediate responses.

They play favorites, valuing loyalty and flattery over competence. They may promote a less-qualified employee simply because that person always agrees with them.

They lack empathy, treating employees like machines instead of human beings. They may ignore real personal emergencies and expect people to “push through” regardless.

They are often absent, avoiding responsibility, avoiding tough decisions, and disappearing when problems arise—forcing the team to act alone.
