A bit of a vent/rant sorry. I am HoD in a department where the mode is white male colleagues, mid-towards-end career ca. 10-15 years older than I. This wasn't honestly too much of an issue before I became HoD but this year since teaching started I keep being mansplained left and right. A colleague felt the need to explain to me in an e-mail what a specific subdiscipline in our field is (a smallish but very visible one these days - think a doctor explaining to another what Public Health is). Another said that we cannot offer a PGT course in a certain field because only colleagues A and B (both male) have expertise in the field... a field on which I have published three books with prestigious publishers. When I try to engage colleagues in discussions about future directions, a large chunk of the meeting is dedicated to stating and paraphrasing the absolutely obvious, as if I couldn't possibly have thought of that (like "if you want to grow PGT numbers you have to come up with an idea for which there is student demand!"). Another colleague even questioned whether I had correctly interpreted post-MAB university guidance (there wasn't really much room for misinterpretation). Is this normal? What do you do to avoid being mansplained? Luckily my line manager did inadvertently witness a couple of instances of colleagues mansplaining me and she was unimpressed at them and very supportive of me - otherwise I don't think I would have dared bringing these things, lest I am imagining things.
