My new job is a part time job share with another woman. So far, I enjoy the job and feel quite confident considering it's a new field. The only issue I'm having is the woman I work alongside. We probably wouldn't socialise outside of work but we get on very well otherwise. She comes across a little hard faced but I find her hilarious.
She's very competitive and it's been noticed by our manager. She's told me in so many words that she feels inferior. I try to communicate clearly and show her everything and anything I learnt but it's becoming quite draining. She becomes easily distracted and makes silly mistakes and it makes me look incompetent.
I was asked a question the other day and I couldn't cover for her without implicating myself.
I mentioned an error she made and she took it really personally - I was telling her for her benefit so she didn't get in shit.
What should I do? Keep quiet and see how things go?
Or AIBU to consider voicing my concerns?
I don't want to seem like I'm causing problems.
