Asked for 3 things before returning to work (covid related)

Yes, I am sick of hearing about Covid also, but here I am with my own story. My back went out and since we had a change in co-workers and I saw people were getting slack with covid safety measures, figured I would ask for three things before I came back (from pt and doctors). * People entering the building to already have masks on* * Air filter changed on schedule, depending on type of filter. * Mask-wearing in common areas where we all breathe the same air or walk through it before being dispersed enough to be safe, per the Public Health Order: “Ensure all employees have face coverings or masks and wear them in the workplace at all times when in the presence of others”  I gave this manifesto (there were a lot of talking points so my boss could answer any question coworkers threw at them) I won't post it unless someone asks me to. I went today after PT to give an already-written note of my update direct from doctor, but instead of using my key, I didn't want to walk in on anyone alone, so I knocked. Coworker answered door without a mask on. My place a of business? A Houseless/Homeless Resource center. One coworker has already had the virus, one of the first 5 in county. Chances are I will be out-numbered and be out of a job -lesson learned, I didn't have a signed contract, never forget that, no matter how much you love the people you work with, which I do, the manifesto said as much. I also relayed that covid is the community assailant, not each other. I would take a bullet for these people, even now, dismayed, disappointed, and probably out of the one time only dream job. I feel like I am being pushed out of a job for being proactive.
