Is AUTHOR wrong in the post ? POST : So a little backstory: I was the first one to join my current team at work close to 2 years ago and we recently added 2 new members about 3 months ago, one external resource and one who moved internally from another group. Let's call the one who joined externally Sam - this one is about her.

To give some context, I am the youngest on this team (I am 24f while Sam is in her thirties), but I am usually in charge of training since I have joining seniority. I trained pretty much everyone on my team so far with no issues. There is a learning curve with the job so I prepare myself to be patient. Most took some time to adjust, but ended up being phenomenal additions to the team to the point I have developed a high respect for my manager's hiring ability.

Now Sam joins and to be frank, I have no idea what prompted my boss to hire her. It has been months now and basic material is still going over her head. But it's not even just that she is plain bad at working because maybe she'll eventually get it, her mannerisms are that of a child's. For instance, I was nibbling on a snack as I was working when she grabbed it with her hands and said she wanted some and tore a piece of it to eat it without my consent. When she has an open cubicle to sit at (she doesn't have an assigned seat yet due to office reconstruction), she decides to sit with me in my cubicle because she wants to ask me questions about everything. When I ask her to work on something with me (another team member has complained that she isn't doing her share of work), she says she doesn't have the bandwidth because she's writing one email. Plus, she asks very personal questions, asking for photos of my family and boyfriend. I guess she's just being friendly, but it makes me uncomfortable in the workspace.

With all that being said, she is such a sweet lady and I know she does try her best to improve. But I'm starting to lose hope. These days, I think she can tell that I have an attitude change (I still try to help her when it's needed) and is even a bit intimidated to approach me. It's only a matter of time before my boss discusses with me on her progress and I don't think I have any positive things to say. As the senior member, I'm afraid my words may even cost her the job.

So, AITA for losing faith in my coworker and possibly about to express to my boss that she is terrible at her job?
