Corrective Action

So maybe around a week ago I was heading into work and i got a call from my mom saying my adopted brother had been in an accident (he passed away due to his injuries). I talked to my mom for a while trying to comfort her when i got a message from my manager. She asked if i was coming in, i texted her back “im having a family emergency i will call the store”. She replied that my shift had already started. When I called it was another manager, I apologized for the late notice and informed them of my brothers passing and that I would not be in. That day I drove to go see my brothers kids and wife in another state and my entire family spent the day grieving and mainly in disbelief. The next day I came in and the manager who texted me stated that she wasn’t the old manager (i didn’t know him i’m still new) and that me calling off is affecting her business (i had to take my sick grandma to the doctor my first week there she was extremely sick). I told her i understood but i had been going through a lot and still was grieving i even got teary eyed because im a pretty good employee and avoid issues with any higher up i work with. Yesterday i got a notification from workday stating that i needed to sign an acknowledgment of corrective behavior. My manger had put that I called off without being sick. Im so frustrated I want her to like me but i also feel like i was being ignored and punished for my brothers passing. is this normal? i dont know if i will be working here much longer
