Microsoft

There is a lot of flexibility, and most of the managers do not micromanage. To that extent, it is good. The company has flexible work hours and no attendance policy. Employees can walk in any time and leave any time.

The manager's opinion is the highest and the last thing. The manager can make or break one's career.

If the manager is playing a foul game with an employee, there is very little that can be corrected. Because, at the end of the day, what the manager says is final.

The skip-level manager or top management does not have any time to oversee if some managers are playing a foul game, pushing their favorites to higher positions, and spoiling other employees' chances.

Though there are systems in place to check this kind of problem, largely they are defunct and only for namesake. Wake up, Microsoft.
