I think it comes down to two causes: (lack of) trust, and insecurity. Now that I look at that, those might not be two reasons.kind of. It’s definitely not competent management. But competence and trust are completely different. I can be competent, and you can be competent, and I can still not trust you. We can also both be incompetent... or somewhere in between. And still I can not trust you as an employee. Lots of other possible reasons for that.
Also, very important to note that competence for the manager is competence AS a manager. Competence as an employee is as a technician. And the skill sets are not the same.
im not sure I understand what you mean by this. But sure.
It’s also possible that cop management and culture, being closer to a military organization, is not the same as white collar management.
