I'm a Product Manager for a proprietary software. In that role I participate in the "longterm planning" team comprised of our lead Developer, the CTO and myself. I'm the only woman in our 20 person development department. I'm around the same age as the rest of the team, with the CTO being much older. The CTO is very involved and frequently meets with Dev and other team members about special projects etc without me there.
Recently, in email threads between Dev and CTO where I am copied (but not actively replying), Dev has @ tagged me "Can you please add this to our agenda for next meeting"?
At first I corrected him via replying to the email that CTO owns that recurring meeting and its agenda, and I ask CTO to add it in my reply. The next month Dev tagged me again to update the agenda and I reminded him again.
Then today, Dev began an email thread with CTO regarding some application decisions. CTO replied with a "Next steps should be a meeting of the longterm planning team." Dev then replied to CTO's email and @ tagged me to "please schedule a meeting that works for our schedules."
I'm feeling a bit like Dev is treating me as CTO's assistant, but I'm not sure how to politely push back or if I should push back. It feels strange to be tagged at the end of a conversation thread and only for the purpose of scheduling a meeting. It is possible Dev is very busy, but I estimate the time it took him to add me to the email and then tag me is equal to the time it would take to schedule a meeting.
Should I be scheduling these meetings/writing the agendas? If not, how can I politely push back?
