I had an employee try to play the card when I gave her a poor review. I am Jewish and she is Muslim. She went so far and got our Market HR manager involved in it. I had to pull all 100+ reviews of my other Muslim employees that got meets expectations or higher. I pulled all of this TM documented coaching and write ups to prove she warranted a below expectations.
It was extremely upsetting that I had to be interviewed by higher up HR managers about my religious beliefs and had my integrity questioned for a split second.
Luckily, I was able to prove that she was a crap worker and my religion had nothing to due with her ability to perform her job duties.
