I’m 24 and early in my career as a librarian, and (perhaps unsurprisingly) most of my co-workers are closer to my parents’ age than my own. I’ve been at one branch for about a year now, and am finding myself increasingly frustrated with one of my co-workers. She has a son who is around my age and I think she sees me as more of a child than a professional equal. When we work at the desk together, she jumps to answer patron questions that are directed at me and insists on doing tasks that I’m more than capable of doing. When I push back she says not to worry about it and that she doesn’t want me to exert myself. I want to have more professional agency and begin taking on more responsibilities, but I’m not sure how to convey this to her or our boss without making it seem like I’m rebelling against her and her many years of experience. Any advice?
