Hostile work environment?

I’ve worked at my job for over 5 years and have maybe called out once or twice, ever…and never ever have I lied about being sick or anything for that matter. I even worked with covid (unknowingly) because no one would cover my shift. Well 3 hours before my shift this Saturday, I started feeling really gnarly and checked my temp and I had a fever of 102. I texted my manager and let her know I had a fever and felt like a truck hit me so wasn’t sure what to do. I wanted the shift (I picked it up) but I could hardly move my body and had the chills. She replied and said if I couldn’t get it covered I had to come in. I was honestly shocked, not at her lack of empathy but that she would risk me exposing the public and other employees. She didn’t offer to help me try and get it covered or say she hoped I get better or please try to work, nothing. She showed zero emotion and I bartended all night sick as a dog!! One of my customers gave me his jacket because I was shivering and in the morning I get text messages that the bar wasn’t clean enough. I explained I was sick and was offered zero sympathy, he only went on describing how bad the bar looked. I’m not sure what to do but I won’t tolerate this. I felt like absolute death and people who said they couldnt cover me were there drinking!! They made me come in sick AF PLUS they sat on the patio all night drinking with their crying baby running around. So so stupid and disrespectful. At least have the decency to go hang out somewhere else!
