Thank you guys so much for your advice on the linked post. I ended up not saying anything to her. They ended up firing her today and it was so messy and horrible. She was crying and begging to keep her job. My boss was crying afterward in his office because it was hard for him.
My boss ended up explaining to me that they came to the decision they had to fire her because she didn’t tell them about not passing and she was coming in around 10 am and had taken 7 days off since she began a little over a month ago. All together I guess it just pushed them over the edge.
I do feel guilty for not talking to her but I’m trying to remember these were her decisions to make. It’s just that losing a job is so hard.
