I've been having ongoing issues with an overbearing coworker and I'm not sure if I am indeed being too sensitive and I should just "Let Go" or if I should set another boundary...

This week: I took a PTO day to take my father to doctor's appointments. I notified my manager who approved the day off. I didn't feel the need to share my whereabouts with coworkers.

However, around 10 am yesterday, I got a text from my LOUDMOUTH coworker that said something like "Are you OK? You could have let someone know that you weren't going to be here today..."

Here's my issue... She's NOT my manager. My whereabouts really shouldn't concern her especially since our roles don't affect one another. My absence will have no bearing on her completing her duties. So, why did she make it a point to tell me that I should have placed my absence on the team calendar? Our manager didn't say anything about doing that...

So, I wonder if I AM being too sensitive? I do struggle with deciphering concern from pettiness. Maybe she was just being concerned and expressed it in her abrasive manner (although I could have done without the reprimand for not placing my absence on the team calendar). Was she just trying to be annoyingly helpful?

The manipulative codependent in me wants to forward the text to my manager and work on a diabolical plan to get her fired, but I recognize the flaws in the plan...

UGH.... I REALLY don't like this woman.
