I started working with my present organization 3 months ago. It's a very rural, conservative company. I'm in my late 20s and a foreigner of color and the company doesn't exactly have diversity.
My boss hired me due to my educational qualification and I am here to help him on projects and things that the rest of my teammates don't work on, on a day to day basis. I was also hired to train on certain specific things that a co-worker, (let's call her Carla) does. I am her back up as she's approaching retirement (which she dreads.)
Carla has been with the company for 18 years. She knows a lot about the company, the way things work here, and everybody naturally reaches out to her because that's what they are used to, also they might think she's more approachable due to the fact that she's a local. She's mostly pleasant and helpful to the others.
I work hard to do my job and have received positive feedback about my work from my boss, and others. But Carla feels otherwise. She constantly sees the need to micromanage all my activities (especially because she gets copied on all the emails) and is rude to me at times. When asked for training on what she does, she puts it off by saying "I'll help you later, I'm busy" She either feels like I'm threatening her job, or she feels like my work ethic isn't acceptable (due to age or ethnicity)
My boss doesn't know of all this and I'm unsure how to approach my boss. I got laid off from my previous job and it has left me a little under confident and scared. Should I tell him at all or just grin and bear it? I am obviously more disposable than Carla is, to my boss.
