The correct text was: "I'm using a sick day." Full stop.

Once I was at the hospital because my mom went into the ER with septic shock, critical state. As the night went I realized I wasn't going anywhere anytime soon, so I called my manager and told them I wasn't going to be able to come in. Should have stopped there, but in the moment I mentioned that I was with my mom and she was in ICU. The next day I was at work I asked about covering that day with sick time. "Oh, you weren't sick, so I can't give that to you."

Cops and management. Never tell them more than you have to. Managers love taking your time from you, even in the same breathe of talking about how people-centric they are.
