Weak management that uses juvenile tactics to get things done. There is no semblance of professionalism. They don't even attempt to train their employees or help build their careers.
For instance, my current company pays $1,000 to any employee who completes a certain amount of the training they provide. Things like this are the norm at most companies: they care about their employees and pour into them. They communicate clearly with them, support them and give them what they need to excel not just at the company, but for their career. Long-term, this builds an "external network" of people who remain an asset to the company even when they've moved on in their careers.
MBC on the other hand is the opposite of this. They have a network of angry ex-workers. Even current junior employees hate the company and are trying to leave as soon as they are able to. Worst company culture I've ever seen.
None I can think of. They are as bad as they get
To many to list. Just don't work for them. Just don't.
