How do they monitor her?

Question

If a branch manager is on warning from the very high-ups what type of warning do they get and how are they monitored. The branch manager harassed the staff, lied to get people fired, and acted more like a warden, made the staff hate coming to work. One of the people that she fired wrote a letter to the CEO detailing everything the branch manager has done to the staff as well as the customers. The person who was fired first mailed the letter they wrote to the CEO office but really wanted something done about this branch manager so the person that was fired sent the letter to the CEO's home and right after the CEO received the letter the manager was put on warning. The person's ex-coworkers said that the manager is not harassing but still strict. But when the computers went down because it is a new system she treated everyone to lunch. They say she still has her mean moments. So how is she monitored if the higher ups are not in the branch on day-to-day basis. I mean they cannot go by what she tells them.

Answer 1

They have probably planted a monitor in the office. New employee or transferred employee.

Answer 2

They probably aren't directly monitoring her.  They'll wait to see if they get any more complaints from her staff.  I'm surprised that the CEO actually did anything.  Generally they only do something if they're worried the company might get into legal trouble.  Unfortunately it's not against the law for your boss to be a bully - verbally at least.  They're not allowed to hit you, but they can scream at you all they want to.  CEO's don't like to be bothered by stuff like this, so if everything stays quiet, they won't do anything to her.
