i would not respond to teams, nor would I escalate or discuss with anyone else
what I would do is book a meeting with her for 30 mins this week. Call it something like “to discuss errors you notified me of in teams”. Do not engage in discussion with her before or after or explain further. If she rejects meeting you’ve clear indication that she certainly wasn’t trying to help you but just sticking a knife in. Save that rejected meeting notice and escalate if she ever pulls a stunt like that again to you or anyone else
if she agrees to meeting, go ahead. Start by stating you except you made an error. Then ask her what she was trying to achieve by broadcasting it on teams. Don’t interrupt , prompt and ask questions on the why, why, why to get to a point where she can either give you a justification that at least might have made sense to her, or you get to point where she’s clearly lying and stalling to avoid saying she was just sticking the knife in to boast her ego or whatever. Explore her thinking if she genuinely believes she was trying to acheive a legitimate and value adding (business) aim by doing it. Mirror back and show you have listened and understood her .
Then say quite calmly and professionally that, as a professional you would have sorted the immediately issues then booked a private meeting, like one your doing now, to explain the issue/error and impact it had on you and, if needs be vent a bit of frustration within privacy of a closed meeting and then got resolution and an apology . If she was trying to help that would have been most cost effective and efficient way to the business. Tell her that, in your opinion, “shaming” people in public for errors is the least beneficial solution for a profitable or successful business and only serves to send messages to people that other team members cannot be trusted to treat people with the respect they’d expect to be treated with themselves . Tell her that she has your day off , that you have stressed about it, and was that truely her intent?see what she says to thst. Then state that If she genuinely wanted to help, in future she must raise issues with you direct as you would do for errors she made. If she is finding she is picking up crap form you continuously then copy in your manager, or even take her complaint to you manager, but it is not a matter for public consumption and you will not accept people shaming you in public for minor issues. You will not accept her doing this again, with you or for that matter anyone and next time will escalate it with her manager
obviously if she can explain a rather odd and misguided theory on why she did it you may want to alter your response . But you need to state clearly where your boundaries are and make her pause and think. If no one pulls her up she will merely think it is acceptable. It isn’t.
I’ve had this shot before except I wasn’t even copied. A senior manager forwarded the email to me saying you might want to know this was sent out and I’ll be talking with her. I booked a meeting and did the above. She never tried to pull a stunt like that again. I know damn well she was trying to big herself up at my expense. Except I hadn’t made a mistake, her broadcast message was a criticism based on her personal opinion on the way I did my job as a senior manager. I don’t think she realised that most people she sent it too had worked with me too long and had already got their own opinions of me over many years, and just thought she was batshit crazy. But I was angered and frustrated and stressed by it- no one is immune to being publically shamed and criticised. You do need to state your boundaries as I did,
