I just recently lost my 91 year old grandmother to cancer and I have been completely devastated. The day before the funeral I was at work when I dropped a glass (I am a busser for a restaurant chain) and my supervisor became upset with me that I wasn't going fast enough despite me telling him I was currently grieving and emotionally drained. He didn't seem to care about my current state of mind. I came back to work today and found out I was the only busser scheduled despite me still struggling with grief and sadness. It was extremely packed at the restaurant and I would have thought management would have at least have another on due to my circumstances. Obviously, I was very overwhelmed but I tried my best. My supervisor wanted me to clear out a table when I had a bunch of other tasks I needed to do. I told him I was the only busser on and his response was "and" then claimed I was being short and curt with him despite me just being overwhelmed. Now the rest of management thinks I am not a good fit for the position despite me doing a pretty decent job before I knew of my grandmother's passing. I tried to explain that I am only struggling at the moment due to grief, not because I can't handle the job on an ordinary basis. I feel so depressed about my grandmother's death and the fact that I feel like I can't do anything right. I am currently seeking employment elsewhere because I don't think anyone besides the general manager really cares about their co-worker's feelings. Everything I do feels like a mistake.
