How do you train someone who thinks 20 years of experience means they have nothing left to learn?

Multiple things are going wrong in this workplace story shared by u/One_Sell_250. From the start, there's no office manager… and that just sounds completely off. Because of that, when a new employee comes in and someone has to teach them how to do things, another employee is given the task, although it's not their responsibility. And things start to go wrong, and mistakes are made.

The mistakes are not the bad part: we all make mistakes, especially if we're starting at a new job. The problem is the attitude and the way we face the people who are there to teach us what not to do, so that next time we can avoid doing them. This woman, who just joined the company, apparently has 20 years of experience in the field and was not willing to let anyone teach her how to do things. She did what they told her at her past job, thinking it was enough. And, of course, it was not.

The writer said he was with her most of the time, and whenever she did something wrong, she wouldn't listen to him and would defend herself. This leaves no room for improvement, and the employee who's teaching her is very exhausted and not cooperative. And since there's no office manager, he has to complain directly to the owner of the company… 

The worst part of all was when this woman revealed confidential information to a client, something that is never supposed to happen since this is private to the company and their own procedures. If you ask me, after the multiple mistakes and the poor cooperation. I'd have done something to get fired. But that wasn't the case, and she's still working there and doing her own things. If nobody steps in and can stop her, worse things can happen, and more confidential information can be revealed…
