I am a junior associate (1PQE) and I constantly get shouted and yelled at by another senior associate (4PQE). We work closely together and everytime she talks to me she puts on an extremely negative and frustrating front. I tend to get nervous talking and answering her as her pessimism would inevitably affect me. I understand from her point of view, she is frustrated as she needs to constantly check and review my work. I make many mistakes and I understand that my work is not up to standard. However, the workplace seems very toxic for me and I feel stiffled as I cannot do much to improve the situation - its becoming a never ending cycle. What should I do? Is that my fault since I am not meeting up to standards?
