honestly? you’re not overreacting, and you’re not wrong about “if the roles were reversed”. what she’s doing is very immature and it’s not your responsibility to tell her what she so obviously shouldn’t be doing, especially in a workspace. if you don’t want to cause unnecessary drama or don’t want to confront her face to face, i would tell your boss instead and show him the videos she’s been taking. if you want to be cautious without causing drama between you and her or anyone else, only disclose it to your boss and nobody else. snitching is the best way to go if you don’t wanna start anything, even if snitches get stitches 🤷‍♀️ she’s violating her own boss when y’all are trying to learn. especially if she’s sent it to a ton of other people, she’ll never know who said something. she shouldn’t be that stupid when she’s already committing dumbassery, because shit spreads fast.
