“Who was my mentor?”

I’m the only woman in my department. We recently hired two men, one tenure track, one temporary. At a department meeting before they arrived, we discussed who would “take responsibility” for each of them — be a mentor, show the person the ropes, talk to them about their work, etc. Somebody said, “you know, like we did for persons A, B, and C when they got here.” A, B, and C are the three men who were hired at the same time as me (about 5 years ago). I tentatively asked, “Who was my mentor?” because I don’t remember anyone helping me out in that way. Everyone looked surprised as though it had never occurred to them that I should have a mentor. I do remember a discussion at the end of my first year, when my department chair said that if I wanted some mentoring I was free to contact a female professor in English. She was their department chair and “very busy”, but maybe she’d be willing to talk with me. Needless to say, I did not follow up on that half-hearted suggestion. Maybe I should have, but there would have been no overlap in our research interests. I did manage to get tenure last year, but now I’m watching a 1-year hire be wined and dined by his philosophy mentor, and it’s making me pretty angry about the disparity in treatment.
