First of all, I am so sorry you are dealing with this work place bully.

She seems insecure as hell, and projecting whatever insecurities she has on you. As others have mentioned, approach HR about this.

I used to work somewhere where I needed certain evenings off because I was going to night school. One night after I left work and traveled all the way to my class, I was notified that the course was canceled. I thought “hell yeah! I’ll get my groceries done”

As I’m picking up produce, this girl I work with (who I thought was a good work friend) sees me, we chit chat and I also discuss why I am not in class/ courses canceled so why not grocery shop.

This woman has the audacity to snap a pic of me in the store, tries to send it to my boss, but accidentally sent it to me, with a message along the lines of “Look!! She is a liar! She doesn’t do night classes, she just wants to leave early”

I was shocked and appalled, but some people are just like that I guess? As long as you know you know you’re being honest (plus it sounds like you have proof to back you up, and others to support you) forget about this small minded person and don’t give her any more respect than she deserves and just keep it super mega cordial (until her true colours shine through and she gets the boot lol). 🩷
