Hello, I am a female subject matter expert in an external facing role with leadership roles in several key industry associations. I have a very high workload and firm deadlines. When looping in internal stakeholders for communication or feedback on new/revised industry topics, proposals, etc I have to strike a balance of catching attention, informing, specific ask, brief background for context, etc. .. . Everyone is stressed. But there is a male colleague that continuously criticizes me, if I use a smiley face it’s sarcastic, if I request review and feedback by a certain deadline I am being “imperious”, etc. He has a lot of knowledge but is in a different role and may be jealous of my role? I am struggling to remain objective about his unsolicited negative comments aimed at improving me. I feel like he lacks self awareness that his feedback is 10x more negative than my direct please and thank you communications. How can I control my negative internal reaction to his characterization of me? His knowledge is deep, but not always current. I try to engage him personally (beyond group emails) as a valued reviewer and sounding board on certain topics, which is actually part of his job. Advice?
