We have this new employee who has been with us for almost three months. She is having a hard time remembering how to do things. I ask her how things are going and if she understands everything we have taught her and she says yes. The problem is, she doesn't. She is making little mistakes that are causing more work for others. If I ask her if she understands a certain thing she still says yes even if she doesn't. She is very hard to coach and not sure what else I should do.

I started at my work almost 4 years ago and have slowly moved up. I am now in a manager position and one of the things that concerns me is the level of seriousness that some employees might have with me. They all know what my position is but when it really comes down to a situation will they be able to take it as a work situation or will they take it personally? Is there any certain ways that one should handle things like this?
